Convert Millirem to Microsievert

Type the number of millirem that you wish to convert to microsieverts.

1 mrem (millirem) = 10 μSv (microsieverts)

How to Convert Millirem to Microsieverts

The millirem and microsievert are both units of radiation dose. By definition, 1 millirem equals exactly 10 microsieverts. This means to convert millirem to microsieverts, you multiply by 10.

Formula

microsieverts = millirem × 10

Step-by-Step Example

Convert 5 mrem to microsieverts:

1
Convert 5 mrem to microsieverts

We need to convert millirem to microsieverts

2
Apply the formula

Since 1 mrem = 10 μSv, multiply by 10

5 × 10 = 50

Answer

5 mrem = 50 μSv

About These Units

Millirem (mrem)

A millirem (mrem) equals 0.001 rem or 10 μSv. US dosimetry standard: natural background 300-400 mrem/year, occupational limit 5,000 mrem/year, public limit 100 mrem/year above background. Chest X-ray: ~2 mrem.

Microsievert (μSv)

A microsievert (μSv) equals 0.001 mSv or 0.1 mrem. Common exposures: dental X-ray ~5 μSv, chest X-ray 20 μSv, transatlantic flight 40-80 μSv, banana (K-40) 0.1 μSv. Most radiation meters display μSv/h for environmental monitoring.
