Pro Tips
- •Length, weight, volume, area, and speed conversions use a fixed ratio to a base unit, so they scale linearly
- •Temperature conversion is different - it uses an offset formula rather than a simple ratio, since 0° isn't the same starting point across scales
- •Use the swap button to quickly reverse the conversion direction without re-selecting units
- •Volume conversions use US customary units (cups, pints, gallons) rather than UK imperial measurements
Most Popular
Most users convert between metric and US customary units, like meters to feet or kilograms to pounds
When to Use This Tool
Convert ingredient measurements between metric and US customary units, like milliliters to cups.
Convert distances or speeds between kilometers and miles when traveling or planning a route.
Convert lengths, weights, or temperatures between metric and imperial systems for calculations.
Convert body weight or height between kilograms/pounds and centimeters/feet.
How It Works
Choose a category of measurement (length, weight, temperature, volume, area, or speed)
For most categories, convert the input value to a common base unit using a fixed ratio, then convert from the base unit to the target unit
For temperature, apply the appropriate offset-based formula between Celsius, Fahrenheit, and Kelvin
Display the converted value instantly as you type or change units

Frequently Asked Questions
Why is temperature conversion different from the others?
Length, weight, and similar units all use zero as a true starting point, so converting between them is just multiplication. Temperature scales have different zero points (0°C isn't 0°F), so converting requires an offset formula rather than a simple ratio.
Are the volume units US or UK measurements?
This tool uses US customary volume units (US cups, pints, quarts, and gallons), which differ slightly from UK imperial measurements of the same names.
How precise are the conversions?
Results are calculated using standard conversion factors and displayed with up to 6 decimal places, which is precise enough for virtually all everyday and professional use cases.
Is my data sent to a server?
No. All calculations happen instantly in your browser using JavaScript. Nothing you enter is transmitted anywhere.
Can I convert currency with this tool?
No, this tool covers physical units of measurement only. Currency conversion requires live exchange rates, which would need a different, server-connected tool.
