Free · Designed for iPad. Not verified for macOS.
Convert everyday units with memorable examples, practical tables and saved values. Fully free to use — no subscriptions or hidden costs.*
Conversion Buddy is a friendly everyday unit converter that does more than give you a number. It combines exact conversions with memorable examples, practical reference tables and simple explanations, helping unfamiliar measurements make sense.
CONVERT EVERYDAY UNITS
Enter one value and instantly see useful equivalents across temperature, distance, height, weight, speed, area, volume, cooking, fuel economy and tyre pressure.
LEARN USEFUL REFERENCE POINTS
Remember everyday anchors such as 20°C = 68°F, 30 mph ≈ 48 km/h and 180 cm ≈ 5 ft 11 in.
USE TABLES IN EITHER DIRECTION
Start with the units you recognise. Swap tables between centimetres and feet, kilograms and pounds, kilometres and miles, mph and km/h, bar and psi, square metres and square feet, litres and pints, and more. Each direction uses clear, rounded starting values.
SAVE YOUR OWN VALUES
Keep useful personal references in My Data, including heights, baggage allowances, tyre pressures, room sizes and cooking measurements. Add a name, group, notes and pin important values.
CHOOSE YOUR REGION
Use UK mixed, USA or Metric preferences so the app starts with units that feel familiar.
EXPLORE THE STORIES BEHIND MEASUREMENTS
Discover why 5 ft 4 in is not 5.4 ft, why UK and US pints differ, why lower L/100 km is better and why horses are measured in hands.
