Unit Converter

This tool converts values between units in the same category — length, weight, temperature, volume, speed, or area — so you can quickly translate measurements from one system to another.

Each unit is defined with a conversion to and from a common base unit (like meters for length or kilograms for weight). To convert between any two units, the calculator first converts your input to the base unit, then converts that base value into your target unit, which keeps the math simple and accurate no matter which pair you choose.

Example: Converting 5 miles to kilometers first converts miles to meters using the base factor (5 × 1609.344 = 8046.72 m), then converts meters to kilometers (8046.72 / 1000 = 8.05 km).
