Formula and method
The grad To rad Converter converts values between Gradian (grad) and Radian (rad).
Conversion factor: 1 Gradian (grad) = 0.015707963 Radian (rad).
Angular unit conversions translate planar rotation between circular degrees, mathematical radians, gradians, and arc subdivisions.
Examples
- Convert grad to rad instantly.
- Swap units or choose another unit from the same group.
- Example: 1 grad converts to 0.015708 rad.
- Angles are measured in degrees (°) for everyday geometry, navigation, and construction; radians (rad) for mathematics and programming (Math.sin/cos require radians); gradians (grad/gon) for surveying (400 grad = full circle); and arcminutes/arcseconds for astronomy and GPS precision.
Understanding Gradian to Radian Conversion
Converting values from Gradian (grad) to Radian (rad) is a unit transformation in the angle measurement system. 1 Gradian (grad) equals exactly 0.015707963 Radian (rad).
When this conversion matters: Angles are measured in degrees (°) for everyday geometry, navigation, and construction; radians (rad) for mathematics and programming (Math.sin/cos require radians); gradians (grad/gon) for surveying (400 grad = full circle); and arcminutes/arcseconds for astronomy and GPS precision.
Precision & standards: Angular unit conversions translate planar rotation between circular degrees, mathematical radians, gradians, and arc subdivisions. SpecWhale uses official SI and imperial conversion factors, computed with 64-bit IEEE 754 floating-point arithmetic entirely in your browser — no data is sent to any external server.
