Radians to milliradians converter
Milliradians (mrad)
1 radian = 1,000 milliradians
How to convert radians to milliradians
mrad = rad × 1000
Multiply the number of radians by 1000 to get milliradians. Going the other way, divide by 1000 (or multiply by 0.001).
One radian is exactly defined as 1000 milliradians (to 12 significant figures), and one milliradian is 0.001 radians.
Worked examples
- Convert 5 radians: 5 × 1000 = 5,000 5,000 milliradians.
- Convert 12.5 radians: 12.5 × 1000 = 12,500 12,500 milliradians.
- Convert 250 radians: 250 × 1000 = 250,000 250,000 milliradians.
