Compound Unit Converter

The advanced converter shows all unit values for a category simultaneously — type in any field and every other unit updates in real time. You can also build compound units by adding multiplier or divider dimensions.

Click "× Add Dimension" or "÷ Add Dimension" to multiply or divide by another unit category. For example, start with Length and divide by Time to get Speed. Add Mass times Length divided by Time squared to get Force. The tool recognizes common combinations and shows named units.

Length, Mass, Time, Temperature, Volume, Energy, Pressure, Data, Force, and Power. Over 100 individual units are supported across all categories.

Preset buttons instantly set up common compound units: Area, Speed, Acceleration, Force, Energy, Power, Pressure, and Density. Each configures the primary category and modifier dimensions automatically.

Temperature scales use offsets (e.g., 0°C is not "no temperature"), so multiplying or dividing by temperature is not physically meaningful. Temperature works as a standalone category but is excluded from compound dimensions.
