About the engineering unit calculator
Convert between common engineering and CAD units across length, area, volume, mass, force, pressure, torque, speed, temperature, angle, and power. Search units by name, symbol, or alias.
How it works
Each dimension uses a base unit (or Kelvin for temperature). Values convert through that base, then into your target unit. Changing the from-unit within a dimension preserves the physical quantity by recalculating the displayed value.
Precision
Results are formatted with up to 12 significant digits, trimming trailing zeros. Very large or very small values may be shown in scientific notation when needed.
Limits
Conversions are deterministic and based on standard conversion factors. Temperature uses absolute-scale formulas. Cross-dimension conversions (for example length to mass) are not supported.
Privacy first
All calculations run locally in your browser. Nothing you type is sent to a Dockzio server.
