Convert Kilorad to Millirad

Convert kilorads to millirads by entering a value below.

1 krad (kilorads) = 1000000 mrad (millirads)

How to Convert Kilorads to Millirads

The kilorad and millirad are both units of radiation dose. By definition, 1 kilorad equals exactly 1000000 millirads. This means to convert kilorads to millirads, you multiply by 1000000.

Formula

millirads = kilorads × 1000000

Step-by-Step Example

Convert 5 krad to millirads:

1
Convert 5 krad to millirads

We need to convert kilorads to millirads

2
Apply the formula

Since 1 krad = 1000000 mrad, multiply by 1000000

5 × 1000000 = 5000000

Answer

5 krad = 5000000 mrad

About These Units

Kilorad (krad)

A kilorad (krad) equals 1,000 rads or 10 grays. Used in electronics radiation hardening: commercial chips fail at 1-10 krad, radiation-hardened: 100+ krad, space-grade: 300+ krad total ionizing dose (TID) tolerance.

Millirad (mrad)

A millirad (mrad) equals 0.001 rad or 10 μGy. Used in medical dosimetry: dental bitewing 0.5-2 mrad, chest X-ray 10-20 mrad. Provides convenient scale for diagnostic imaging dose specifications.
