About this tool
Cooking, travel, fitness and DIY all mix metric and imperial units. The converter covers the most useful categories with live results as you type.
When to use it: recipes, distances, weights and temperatures from foreign sources.
Frequently asked questions
Which categories are included?
Length, weight, temperature, area, volume, speed, time, data storage, energy and pressure.
Can I convert temperature the same way as other units?
Temperature uses proper conversion formulas (for example, °F = °C × 9/5 + 32), not a simple multiplier, so conversions are exact.
Can I convert across categories, like kilograms to liters?
No — those measure different things (mass versus volume). Conversions happen within a category; crossing categories needs extra information like density.
Are both metric and imperial covered?
Yes — kilometres to miles, kilograms to pounds, litres to gallons, Celsius to Fahrenheit and the rest, in both directions.
Why is temperature conversion different?
Celsius and Fahrenheit have different zero points, so the formula includes an offset, not just a multiplier — the tool applies it correctly.
How precise are the results?
Exact conversion factors are used (for example 2.54 cm per inch), with sensible rounding for display.
