Convert units of acceleration, angle, area, energy/work, force, coefficient of heat transfer, length, mass, mass density, mass concentration, power, pressure/stress, time, velocity, viscosity, volume and temperature.

The conversion factors are based on data published in the "Guide for the Use of the International System of Units" by B. N. Taylor of the Physics Laboratory, National Institute of Standards and Technology Gaithersburg, MD20899-0001, 1995.

Are you missing one or more conversions? Write me an e-mail! If you don't see the conversion applet above, it might be necessary to update your Java™ Virtual Machine first.

Since I am only human, I can't guarantee the correctness of the programmes results! So please check them if there is a risk that incorrect results might cause damage. If you find a bug or if you have any suggestion for improvement, I would be very grateful for writing me.
