Unit Converter: Measurements

A fast, offline unit converter that does the math properly. Type one value and instantly see it in every unit of the category at the same time — no back-and-forth, no waiting.

EVERY UNIT, ONE APP
• Length, mass, temperature, area, volume, speed, time, data, energy, power, pressure, angle and fuel economy
• Type once and read your value in every unit of the category at a glance
• Tap any unit to make it the target, or swap source and target with one button

CONVERSIONS DONE RIGHT
Most converters only multiply by a factor — so they get temperature and fuel economy wrong. This one uses a real conversion engine:
• Temperature is exact: °C, °F and Kelvin
• Fuel economy is exact: L/100km, km/L and mpg (US & UK) — even the inverted ones
• Adaptive number formatting, so results read cleanly without floating-point tails

BUILT FOR EVERYDAY USE
• Pin the conversions you use most for one-tap access on the Saved tab
• Recent conversions are remembered automatically
• Adjust significant digits to trade precision for readability
• Light, dark and auto theme

PRIVATE & OFFLINE
• 100% offline — no internet needed, ever
• No sign-in, no account, no tracking
• Your pins and settings stay on your device

Whether you're cooking, studying, travelling, doing DIY, or working with data sizes, this is the only converter you need — fast, accurate and out of your way.
