Frequently asked questions
- Length, weight/mass, temperature and volume, each with the common metric and imperial units for that category — e.g. metres, feet, kilograms, pounds, Celsius, Fahrenheit, litres and gallons.
- Length, weight and volume are simple multiplicative conversions, but temperature scales (Celsius, Fahrenheit, Kelvin) have different zero points, so the tool applies the correct offset-and-scale formula for each pair rather than a plain ratio.
- Conversions use exact standard conversion factors and are displayed rounded to a sensible number of decimal places — precise enough for everyday, cooking, fitness or DIY use.
