About the Angle Converter
The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
degrees → radians: rad = deg x pi/180
radians → degrees: deg = rad x 180/pi
degrees → arcminutes: arcmin = deg x 60
degrees → arcseconds: arcsec = deg x 3600
degrees → gradians: gon = deg / 0.9
Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.
Formula & How It Works
The calculation applies the following relations exactly as recorded in the metadata: degrees → radians: rad = deg x pi/180 radians → degrees: deg = rad x 180/pi degrees → arcminutes: arcmin = deg x 60 degrees → arcseconds: arcsec = deg x 3600 degrees → gradians: gon = deg / 0.9 Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.
Worked Examples
Example 1: 90° Right Angle to Radians
Inputs
With Angle Value = 90 and From Unit = degrees ( deg) as the stated inputs, the result is Degrees = 32,400 deg, Radians = 565.486678 rad and Arcminutes = 1,944,000 ′. Each value corresponds to the declared output fields.
Example 2: GPS Coordinate: 40°42′46″ (NYC latitude)
Inputs
With Angle Value = 46 and From Unit = arcseconds (″) as the stated inputs, the result is Degrees = 0.012778 deg, Radians = 0.000223 rad and Arcminutes = 0.767 ′. Each value corresponds to the declared output fields.
Example 3: Rifle Scope: 5 mrad adjustment
Inputs
With Angle Value = 5 and From Unit = milliradians (mrad) as the stated inputs, the result is Degrees = 0.286479 deg, Radians = 0.005 rad and Arcminutes = 17.189 ′. Each value corresponds to the declared output fields.
Example 4: Construction Slope: 1 gradian
Inputs
With Angle Value = 1 and From Unit = gradians (gon) as the stated inputs, the result is Degrees = 0.9 deg, Radians = 0.015708 rad and Arcminutes = 54 ′. Each value corresponds to the declared output fields.
