Real-World Context
1 µrad is roughly the telescope tracking offset
Step-by-Step
1. Start with 1,500 µrad. 2. Since 1 micro-unit = 1/1,000th of a milli-unit, divide by 1,000. 3. 1,500 ÷ 1,000 = 1.5 mrad.
Formula Used
÷ 1,000 (micro = 10⁻⁶, milli = 10⁻³)

Quick µrad to mrad answer

Conversion

1 µrad = 0.001 mrad

Rule

divide by 1,000

Example

1,500 µrad = 1.5 mrad

microradian to milliradian formula

Milli is 10^-3 and micro is 10^-6. They are three powers of ten apart, so every µrad to mrad conversion uses the exact factor 1,000.

mrad = µrad ÷ 1,000
1,500 µrad ÷ 1,000 = 1.5 mrad

Understanding microradians and milliradians

A microradian (µrad) is 10⁻⁶ of the base unit (radian) and a milliradian (mrad) is 10⁻³. They sit three powers of ten apart, so going from µrad to mrad means dividing by exactly 1,000 — move the decimal point three places to the left.

Microradians describe beam divergence, interferometer alignment and telescope pointing. A good HeNe laser diverges around 1000 µrad, while spacecraft attitude control and synchrotron optics work in the single-µrad range.

This calculator shifts the decimal exponent rather than multiplying in binary floating point, so 1,500 µrad returns exactly 1.5 mrad — not a value with a trailing rounding error.

Common µrad to mrad mistake

MOA and mrad are different angular units — 1 MOA ≈ 0.291 mrad. A scope sold in MOA does not convert to mrad by shifting a decimal point, and mixing the two is why a rifle walks off zero.

When to use µrad vs mrad

microradians and milliradians are used for ballistics, laser beam divergence, astronomical observations, and precision alignment. Use the larger milli unit when the number becomes easier to scan, and the smaller micro unit when you need finer detail.
