Radians to centiradians converter
Convert radians (rad) to centiradians (crad). Calculate any value, follow the unit-factor steps and check a conversion table.
Updated · How we checkUse a decimal point, such as 2.5. Enter a value in rad; the result is in crad.
Formula
Worked example
Convert 1 rad to crad:
1 rad ≈ 100 crad
Multiply your rad value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

What radians measure
Radians (rad) represent plane angle. One unit equals 10^0 rad. A radian is the plane angle subtended by an arc whose length equals the radius.
Reading the result in centiradians
Centiradians (crad) represent plane angle. One unit equals 10^-2 rad. A radian is the plane angle subtended by an arc whose length equals the radius.
Where this conversion helps
Scale an angular measurement without changing its geometric meaning. A full turn is 2π radians. Radians differ from steradians, which measure solid angle.
How the scale changes
The input unit has a factor of 1e0 rad; the output unit has a factor of 1e-2 rad. Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.
Reading very small or large results
Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
