Convert Microroentgen to Microgray

Input the number of microroentgens you want to convert to micrograys.

1 μR (microroentgens) = 0.00877 μGy (micrograys)

How to Convert Microroentgens to Micrograys

The microroentgen and microgray are both units of radiation dose. 1 microgray equals 114.02508552 microroentgens. This means to convert microroentgens to micrograys, you divide by 114.02508552.

Formula

micrograys = microroentgens ÷ 114.02508552

Step-by-Step Example

Convert 5 μR to micrograys:

1
Convert 5 μR to micrograys

We need to convert microroentgens to micrograys

2
Apply the formula

Since 1 μGy = 114.02508552 μR, divide by 114.02508552

5 ÷ 114.02508552 = 0.04385

Answer

5 μR = 0.04385 μGy

About These Units

Microroentgen (μR)

A microroentgen (μR) equals 0.001 mR. Used in environmental radiation monitoring, radon measurements, and low-level contamination surveys. Natural background: 10-20 μR/h typical. Sensitive ion chambers measure in μR/h.

Microgray (μGy)

A microgray (μGy) equals 0.001 mGy or 0.1 mrad. Chest X-ray: ~20 μGy. Panoramic dental X-ray: 10-20 μGy. Used for specifying doses from diagnostic imaging with minimal exposure. One gray = one million micrograys.
