How to Convert Gradians
To convert gradians to another unit of angle, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[2]
You can find the conversion factors for gradians in the conversion table below.
Then, multiply the angle measurement by the conversion factor to find the equivalent value in the desired unit of measurement.
gradians × conversion factor = result
You can also use a calculator, such as one of the converters below, for the conversion.
