Currency and unit converters
Convert money between more than 30 currencies using daily reference rates from the European Central Bank, and convert units of length, weight, temperature, volume, area, speed, time, data storage, pressure and energy using exact international definitions.
When to use each converter
- The Currency Converter is ideal for travel budgets, online shopping from abroad, freelance quotes and checking the margin your bank adds to transfers.
- The Unit Converter handles recipes (cups to milliliters), travel (miles to kilometers), body measurements (pounds to kilograms, feet to centimeters), DIY projects and technical units such as PSI, kWh and gibibytes.
Accuracy you can rely on
Unit conversions use exact factors defined by international agreement, for example 1 inch is exactly 2.54 cm and 1 pound is exactly 0.45359237 kg, and results are shown to eight significant digits. Exchange rates are official daily reference rates, which are perfect for planning and accounting but are not live trading prices; banks and card providers add their own margin.
