EasyUnit
Read full descriptionHide full description
Type one value and every other unit is already on screen. There is no "from" and "to" to pick first: kilograms, pounds, grams and ounces sit there together, and they all update as you type. Tap a different card to type in that unit instead. Touch and hold a card to copy its value. It works offline and there is no account. NEW IN 3.0 — A keypad made for converting: add, subtract, multiply and divide right in the field, so "2 × 1.5" cups turns straight into grams — Negative values with ±, for temperatures below zero — Every category on one screen, in groups, with search by unit name or symbol: type "psi" and you land in Pressure — Pin the categories you use, and recent ones stay one tap away — Choose which units each category shows, and in what order FREE CONVERTERS — Length, mass, temperature, volume, speed, area, data and time — Metric, imperial and SI units — Every card shows how its unit relates to the one you typed, like "1 in = 2.54 cm" — Copy a single value, or the whole line ("12 in = 30.48 cm") to paste into a message — Light and dark themes PRO PACK — Cooking: cups to grams by ingredient. A cup of flour is 120 g, a cup of honey is 340 g — Oven: Celsius, Fahrenheit and gas mark, plus the wording recipes use ("Moderate", "Hot") — Shoes: EU, US men's, US women's, UK and centimeters — Clothing: XXS to XXXL across EU, US and UK — Engineering: pressure, energy, power, force, torque, angle and fuel economy Sizes and oven settings are charts rather than formulas, which is why a calculator cannot work them out for you. PRIVATE BY DEFAULT Every conversion happens on your device, and the values you type never leave it. No account, no ads. EasyUnit Pro Pack is a one-time purchase, not a subscription. It unlocks the cooking, oven, shoes, clothing and engineering converters, plus any category added later. The free converters have no limits and no ads. The price for your region is shown in the app before you buy. Terms of Use (EULA): https://apps.tmkm.dev/easyunit/terms Privacy Policy: https://apps.tmkm.dev/easyunit/privacy Made for anyone shopping across EU and US sizes, cooking from a recipe written in the wrong units, or working in units a calculator has never heard of.

Verdict
The clearest difference is ads: EasyUnit at none against US Unit Converter's shown. EasyUnit also leads on update cadence (every 3 months vs every 6 months). US Unit Converter's advantage is device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.
