- ✓ Memorable everyday examples
- ✓ One value, several useful equivalents
- ✓ Intelligent tables with round values
- ✓ Save personal references in My Data
Conversions and examples are practical everyday guidance. Check official, safety-critical or product-specific information where accuracy matters.
More than just another number
Most conversion apps provide an answer. Conversion Buddy also helps you understand what the answer means and remember useful reference points.
↔
Convert exact values
Enter one value and see several useful equivalents together instead of repeating the same calculation.
▦
Use smarter tables
Switch direction and rebuild tables around useful round values in the unit you recognise.
★
Keep My Data
Save baggage limits, tyre pressures, personal measurements, room sizes and other useful values.
Learn the values worth remembering
You do not need to memorise every conversion. A small set of useful anchor points makes unfamiliar units much easier to understand.
68°F
A pleasant everyday weather reference.
≈ 48 km/h
A familiar road-speed comparison.
≈ 350°F
A common cooking reference point.
≈ 5 ft 11 in
A useful height comparison.
Convert exact values
One input, several useful equivalents
Choose a category, enter a value and see the equivalents people actually use. Your region profile helps select a sensible starting unit.
- Temperature, distance, height, weight and speed.
- Area, volume, cooking and fuel economy.
- Tyre pressure in bar, psi and kilopascals.
- Save useful results directly to My Data.
Reference tables
Useful round values in either direction
Start with kilometres or miles, kilograms or pounds, centimetres or feet. Conversion Buddy rebuilds its tables around practical values for the unit you choose.
Not a simple reversed list
Switching direction changes the starting values too, so a km/h table uses familiar metric anchors instead of awkward conversions such as 48.3 km/h.
Built for the way people really use measurements
Real life is not always simply metric or imperial. Choose a practical region profile and keep the alternative units nearby.
UK mixedMiles, mph, stone, UK pints and Celsius.
USAMiles, mph, pounds, US gallons and Fahrenheit.
MetricKilometres, kilograms, litres and Celsius.
Discover the stories behind the numbers
Explore why 5 ft 4 in is not 5.4 ft, why UK and US pints differ, why L/100 km appears to work backwards, why horses are measured in hands and why Celsius and Fahrenheit meet at −40.
Convert. Understand. Explore.
Simple by design
Conversion Buddy is designed as a friendly everyday tool rather than a specialist engineering calculator.
