Revolutions to Gradians (rev to grad) Converter
1 revolution equals 400 gradians — multiply the number of revolutions by 400 to convert. The gradian (or gon) divides a full circle into 400 equal parts, so one complete turn is exactly 400 grad and the factor is a clean 400.
The formula
To convert revolutions to gradians, multiply by 400:
gradians = revolutions × 400
For example, 10 rev × 400 = 4000 grad. To reverse, divide by 400 or multiply by 0.0025.

Where this conversion is used
Gradians are favored in surveying and some European civil engineering because a right angle is a tidy 100 grad. Converting from revolutions to gradians helps when a rotational measurement expressed as turns needs to feed into survey calculations, mapping software, or instruments calibrated in gons.
FAQ
How many gradians are in a revolution?
One revolution equals 400 gradians. Multiply revolutions by 400 — for example, 10 revolutions = 4000 gradians.
What is the formula to convert revolutions to gradians?
Gradians = revolutions × 400. A quarter turn (0.25 revolution) equals 100 grad, which is one right angle.
How do I convert gradians back to revolutions?
Divide by 400, or multiply by 0.0025. So 800 gradians = 2 revolutions.
Is the conversion exact?
Yes. A full circle is defined as 400 gradians, so the conversion is exact with no rounding.
