Advanced Engineering Unit Converter
Convert engineering and professional measurement units with compatible units grouped clearly by measurement category.
Choose compatible units and enter a value to see the conversion.
How the converter works
Each category converts through a defined base unit so incompatible measurements are never mixed. Linear engineering units use fixed factors, temperature uses affine scale-and-offset conversion, and fuel economy uses reciprocal conversion where required.
For pressure work, confirm whether the value is absolute or gauge pressure. For flow, density, viscosity and thermal properties, also confirm any reference temperature, pressure or standard-condition convention required by your calculation.

Formula source and acknowledgement
Relationship used: Convert between compatible units by applying the defined scale and offset for the source and destination units.
The conversion basis follows Ambler Thompson, Barry N. Taylor, Guide for the Use of the International System of Units (SI) (2008), National Institute of Standards and Technology.

Limits of use for this relationship
- Source and destination units must represent the same physical quantity.
- Pressure conversion changes units only; it does not convert gauge pressure to absolute pressure.
- Temperature conversions must apply offsets as well as scale factors.
