Metric/Imperial Conversion Tables

Use these conversion tables to perform common conversions involving units of length, area, volume, weight, pressure, density, speed, flow rate, torque, temperature, and angles. Enter a known value in the appropriate edit box and press the corresponding “calculate” button (immediately below the edit boxes) to convert to the remaining units.

Please note that some numbers may be displayed in scientific notation. Scientific notation displays very large or small numbers as equivalent powers of 10 (represented by the letter E).
