Common unit converters

Unit conversion is the process of converting a quantity expressed in one unit to another. This is done with conversion factors—multipliers that express the relationship between the original unit and the desired unit. For example, you can use a conversion factor to convert a volume measurement in gallons to liters or vice versa.

This page contains calculators you can use to perform unit conversions for a variety of measurement types, including common conversions such as those for length, volume, temperature and pressure as well as conversions for engineering, fluid and light applications.


Engineering converters

The following conversion factors address engineering measurements of acceleration, density and torque. Converting these measurements between different units may be useful in machine design or in the characterization of equipment such as stirred bioreactors.

Fluids converters

These calculators convert between measurements relevant to fluid handling, such as flow, concentration, viscosity and permeability. Whether you are performing quality control or determining the appropriate flowmeter or pump for your application, converting your measurements into the appropriate units will make your calculations easier.

Light converters

These calculators for measurements of luminance, illumination, frequency and wavelength convert between a variety of units and can be especially useful for calculations regarding imaging or photometry.
