How to Convert Gradians to Degrees

Protractors are often used to measure angle

Convert gradians to degrees with this simple formula:

degrees = gradians × 0.9

Converting a gradian angle measurement to a degree measurement involves multiplying the angle by the conversion ratio to find the result. One gradian is equal to 0.9 degrees, so to convert simply multiply by 0.9.

For example:
5g = (5 × 0.9) = 4.5°

Gradians and degrees are both units used to measure angle. Learn more about angle and find more angle measurement conversion calculators. Gradians are an angle measurement and can be abbreviated as g, for example 1g. Degrees are an angle measurement and can be abbreviated as °, for example 1°.

Degrees can also be expressed using minutes and seconds as an alternative to using the decimal form. Minutes and seconds are expressed using the prime (′) and double-prime (″) characters, although a single-quote (') and double-quote (") are often used for convenience.

One minute is equal to 1/60th of a degree and one second is equal to 1/60th of a minute.

There are 360 degrees in a revolution, or circle. 360 has 24 divisors, and is easily divided by 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120 and 180. This makes it a fairly easy number to work with. There are also 360 days in the Persian calendar year, and many theorize that early astronomers used 1 degree per day.

Protractors are commonly used to measure angles in degrees. They are semi-circle or full-circle devices with degree markings allowing a user to measure an angle in degrees. Learn more about how to use a protractor or download a printable protractor.

A grad, more specifically a gradian, is equal to 1/400 of a circle or 9/10°. The grad simplifies the measurements of right angles, as 90° is equal to 100 grad.
