Unit Conversion: kg to lbs, cm
Celsius, Fahrenheit, km, miles
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Type a number, read every unit at once - kg, lb, oz, stone, or km, miles, °C, °F. No menus, no direction switch. 20 categories with currency and size charts.
Unit conversion with the answer on screen before you ask. Type a number and read it in every unit of the category at once - kg to lb, lb to kg, km to miles, cm to inches, feet to meters, Celsius to Fahrenheit. There is no "from" list and no "to" list to tap through first, and no direction to switch. You open the app, the keypad is already there, and so is the answer.
WEIGHT, THE SHORT WAY
• kg to lb, lb to kg, kg to stone, lb to oz, g to oz - all live at the same time
• Stone and pounds behave as one pair, the way a British scale reads them
• The value and the units you used last are waiting for you next time you open the app
LENGTH, DISTANCE, TEMPERATURE
• Metric conversion: km, miles, meters, feet, inches, cm and yards on one list
• °C, °F and kelvin, converted by the real formula rather than a rough factor
• mph and km/h, liters, gallons, cups and milliliters work the same way
SEVENTEEN CALCULATED CATEGORIES
Weight, length, temperature, time, speed, area, volume, data storage, angle, data transfer, energy, force, fuel economy, power, pressure, torque and currency. Every category works like the weight one: one keypad, one list, every unit updating together. Search any unit by name or symbol and it opens straight away - type "oz", "stone" or "fahrenheit" and start converting.
CURRENCY THAT WORKS OFFLINE TOO
Rates for the major currencies are built into the app, so the very first conversion works before the phone has seen a network. Once online, they are refreshed once a day from Frankfurter, which publishes central bank reference rates. They are indicative rates for a holiday budget or a foreign price tag, not a trading terminal. Rates: Frankfurter / central banks.
CLOTHING SIZE CHARTS
Shoes, trousers and tops are reference tables rather than formulas: US, EU, UK and international columns side by side, for women, men, kids, and babies for shoes.
DETAILS THAT MAKE IT FAST
• Copy, paste and share the whole conversion - "12 m = 39.3701 ft" - from the actions panel
• A haptic click as the unit dial passes each unit
• Light and dark themes, an accent colour of your choice
• 30 interface languages
• Exact factors, not rounded shortcuts: 1 lb is 0.45359237 kg, 1 inch is 2.54 cm, 1 mile is 1.609344 km. Small numbers stay readable instead of collapsing into scientific notation.
