About this tool
Convert between units of length, area, volume, mass, speed, temperature, pressure, energy, power, data, angle, time, force and fuel economy.
Every unit is defined once relative to an SI base unit, so a conversion goes from → base → to. Temperature and fuel economy use exact formulas instead of a single factor.
Formula: value × factor(from) ÷ factor(to)
Example: Quantity = Length, Value = 1, From = Metre, To = Foot → Result = 3.28084.
US and imperial gallons, cups and fluid ounces differ — pick the right one. Data sizes show both decimal (kB = 1000 B) and binary (KiB = 1024 B) units.
Quick steps
- Enter your values — every field shows its unit.
- Press Calculate (or Try an example to see how it works).
- Read the results and copy them if you need them elsewhere.
The calculation runs in your browser. Nothing you type is sent to 1CLIK.
