MyUnitConverter
A fast, shareable unit converter with 77+ categories and live results.
Tagline
77+ unit converters, instantly
Every measurement, one fast converter
The technical unit tool Google misses
Copy, share, and move on
The conversion tool built for every measurement, not just the obvious ones.
The product’s breadth is the standout feature: beyond basic length and temperature, it includes torque, density, typography, illumination, fuel consumption, and data transfer rate.
A better alternative to Google’s built-in converter when the task gets technical.
The page explicitly contrasts itself with Google, and the product supports specialist categories Google doesn’t cover, plus formulas, tables, and shareable URLs.
The fastest way to get an exact answer, copy it, and move on.
Live typing, keyboard shortcuts, local history, and no-account access position it as a frictionless utility for repeat quick conversions rather than a full app.
Primary user
Students, engineers, and working professionals who need quick one-off unit conversions without installing software
ICP #1
Mechanical engineer comparing torque, pressure, and power units during spec reviews
Pain
They constantly bounce between newton-meters, pound-feet, psi, bar, watts, and horsepower while reading datasheets and vendor docs, and browser searches break their flow.
Why this solves
MyUnitConverter keeps the relevant engineering categories in one place, shows formulas, and supports exact shareable URLs for repeated conversions and team handoffs.
ICP #2
High school or university student doing homework in science, physics, or chemistry
Pain
They need fast answers for Celsius/Fahrenheit, meters/feet, grams/ounces, and area/volume conversions without getting lost in formula mistakes.
Why this solves
The product gives instant results, visible formulas, and common everyday conversions in a simple UI that reduces calculation errors and saves time.
ICP #3
Content SEO manager at a niche utility site looking to capture conversion-intent search traffic
Pain
They need high-volume, long-tail pages for specific queries like 'kg to lbs' or 'mph to kph' that are reusable, fast, and easy to bookmark/share.
Why this solves
The app already has dedicated conversion slugs, FAQ content, and category pages designed around search intent, making it a strong template for conversion-led SEO.
Strengths
- +Clear value proposition above the fold with concrete examples like cm→inches and kg→lbs
- +Strong breadth of categories, including niche technical conversions that many competitors ignore
- +SEO-friendly structure with dedicated category pages, FAQs, formulas, and internal links
Weaknesses
- −The homepage is overloaded with link lists and category tiles, which feels more like an index than a product experience
- −It leans too hard on broad claims like 'speed, accuracy, and clarity' without proving accuracy visually
- −The competitive comparison to older tools reads defensive and dated rather than differentiated by design or workflow
- −The repeated keyword-heavy copy makes the page feel optimized for search more than for trust or conversion
- −No visible social proof, usage stats, testimonials, or brand trust signals
- −The truncated FAQ content suggests the page may be incomplete or not polished
Fix these
- Replace some of the homepage link density with a cleaner hero demo showing instant live conversion and swap/copy actions
- Add proof points for accuracy, such as exact conversion factors, methodology notes, or test coverage badges
- Create persona-based entry points like Engineering, Schoolwork, Cooking, and Web/SEO to make the breadth feel navigable
- Add trust signals: testimonials, uptime/performance claims, and a brief explanation of how formulas are validated
- Use the shareable URL feature more aggressively in the UX and copy, since it is a real differentiator against generic calculators

Every category page shows the formula, a reference table, and FAQs. That makes the result easier to trust and easier to teach.
FAQ
Is this faster than searching Google?
For repeated conversions, yes. You get live results immediately, plus shortcuts for swap and copy, so the workflow stays in one tab.
Does it support technical units?
Yes. Beyond everyday length and temperature, it includes categories like torque, pressure, density, illumination, typography, and data transfer rate.
Can I share a specific conversion?
Yes. Conversion pages use clean URLs like /cm-to-inches and /kg-to-lbs, so you can send the exact conversion context to someone else.
How do I know the results are accurate?
Each category shows its formula and reference table. That way users can verify the calculation instead of trusting a black box.
Do I need an account?
No. It works right away, with local history saved in your browser and optional dark mode for easier long sessions.
I built MyUnitConverter: a fast, shareable unit converter with live bidirectional results. 77+ categories. Not just cm→inches and °C→°F, but torque, density, typography, fuel consumption, and data transfer rate. Try it: /kg-to-lbs
MyUnitConverter is live. Instant unit conversion as you type. Shareable URLs. Keyboard shortcuts. Formula on every page. Built for the moments when you need an answer now, not another search result.
Most converters give you a number and hope you trust it. Mine shows the formula, reference tables, and FAQ on every category page. If I can't explain the math, I don't want the UI. Speed matters. Trust matters more.
The hard part wasn't building cm→inches. It was making torque, density, illumination, typography, and fuel consumption feel as easy as temperature. Same pattern. Different units. Zero extra friction.
Every engineer has done this: open Google search a unit copy a number lose the tab repeat 20 times a day I built MyUnitConverter to keep that loop in one place.
If you're comparing psi, bar, watts, horsepower, and newton-meters, generic search is slow. MyUnitConverter gives you live results, swap/copy shortcuts, and a URL you can send to your team.
Demo that sold me on this idea: 10 cm → 3.94 in Change either side. Hit S to swap. Hit C to copy. That should be the whole experience for 90% of conversions.
Need to send someone kg→lbs? Use a real link like /kg-to-lbs instead of a screenshot or a messy explanation. Bookmark it. Share it. Reuse it. That tiny workflow saves time every day.
This started as a utility for fast one-off conversions. Then it turned into something useful for homework, spec reviews, lesson plans, and SEO pages. Turns out the best tools are boring, specific, and fast.
No account. Dark mode. Local history. Keyboard shortcuts. Shareable links. If a tool is faster than searching, people keep coming back. That's the entire thesis behind MyUnitConverter.
Angle: Technical utility with trust
I shipped a unit converter because the existing ones are optimized for search, not for work. If you're comparing torque, pressure, power, temperature, or data units, the common flow is still annoying: - search a unit - open a result - copy a number - lose context - do it again MyUnitConverter is built to remove that loop. It supports 77+ categories, live bidirectional conversion as you type, shareable URLs like /kg-to-lbs, keyboard shortcuts for swap/copy, local history, and formula displays on every converter page. The part I'm most focused on is trust. A lot of conversion tools feel like black boxes. This one shows the formula, reference tables, and FAQs so the result is not just fast, it's inspectable. If you need quick conversions for engineering, school, cooking, or content workflows, I'd love feedback on the UX and on which categories should be easier to discover.
Angle: SEO and shareable workflow
One of the reasons I built MyUnitConverter is simple: conversion intent is everywhere. People search for kg to lbs, cm to inches, mph to kph, Celsius to Fahrenheit, and a long tail of more technical queries every day. But most tools treat those queries like isolated calculators. I wanted something that works like a product, not an index page. So each conversion has its own shareable URL. Each category page includes the formula, a reference table, and FAQs. And the UI updates live, which matters more than it sounds when you're trying to move quickly. What I learned is that good utility software is mostly about removing tiny moments of friction. A few seconds saved doesn't sound like much until you repeat the task all day. I'm curious how others think about building SEO-friendly pages that still feel trustworthy and designed for real use.
Angle: Broad but navigable breadth
Most unit converters stop at the obvious stuff. Length. Weight. Temperature. That covers a lot, but not enough. Engineers need torque, density, pressure, power, and data transfer rate. Teachers need clean examples that don't invite mistakes. DIYers need quick imperial-to-metric checks. I built MyUnitConverter around that broader reality. It covers 77+ categories, but the real design challenge was making breadth feel simple. The solution was to keep the interaction stupidly fast: type, see results, swap instantly, copy in one keypress, or send someone a direct link. I think a lot of utility products fail because they try to look impressive instead of becoming invisible. This one is supposed to disappear into the task. Would love feedback from people who use conversion tools often: what feels missing, and what would make you trust it more?

77+ unit conversions, live and shareable
Description
Fast bidirectional unit conversion for everyday and technical work. Convert as you type, open shareable URLs, see formulas and reference tables, and use shortcuts to swap or copy results.
Maker's first comment
I built MyUnitConverter because I was tired of the same annoying loop: search a unit, copy a result, lose the tab, repeat. That got old fast when I was comparing specs, writing content, or helping with homework. What I wanted was a tool that felt instant, but also trustworthy. So I added live bidirectional conversion, formulas on the page, reference tables, and shareable URLs for repeat use. The biggest surprise was how many people need more than the obvious conversions. Once you go past length and temperature, the messy stuff shows up: torque, density, illumination, typography, fuel consumption, and data transfer rate. If you've used it, I'd love to know whether the biggest win is speed, trust, or shareability. And if you have a category you wish every converter supported, send it my way.
Pinned maker comment
Would love feedback on two things: 1) which categories are hardest to find quickly, and 2) whether the formula/reference-table presentation makes the tool feel more trustworthy.
