One converter instead of twenty
Length, weight, area, volume, speed, temperature, data and time sit in a single drop-down, so you do not need a different page for every pair of units. Values convert as you type and the swap button flips the direction without retyping anything.
Conversions people look up most
- 1 inch is exactly 2.54 cm, and 1 foot is 30.48 cm
- 1 kg is about 2.205 lb
- 1 mile is 1.609 km
- Fahrenheit to Celsius: subtract 32, then multiply by five ninths
- 1 marla is about 25.29 square metres, and 20 marla make one kanal
Temperature is different
Temperature scales have offset zero points, so they cannot be converted by simple multiplication like metres and feet. The tool routes every temperature through Celsius first, which keeps Kelvin and Fahrenheit results exact.
Frequently asked questions
Which units are supported?
Length, weight, area including marla and kanal, volume with both US and UK gallons, speed, temperature, digital storage and time.
Are the conversion factors exact?
Yes, they use the internationally defined values, for example one inch as exactly 2.54 centimetres.
Why is the answer shown in exponent form sometimes?
Very large or very small results switch to scientific notation so the digits stay readable.
