About this tool
Pick a category, enter a value, and convert between everyday units without looking up a factor table. Length and weight go through a base unit, temperature uses its own formulas so Fahrenheit and Celsius convert correctly, and data sizes use the familiar 1024 steps. It is built for recipes, travel, homework, and quick engineering checks.
Frequently asked questions
Is 1 km really 1000 m here?
Yes. One kilometre converts to exactly 1000 metres, and 32 degrees Fahrenheit converts to 0 degrees Celsius.
Why does temperature need special handling?
Fahrenheit and Celsius do not share a zero point, so temperature needs an offset formula rather than a simple multiply.
