How to Convert Sieverts to Milliroentgens
The sievert and milliroentgen are both units of radiation dose. 1 sievert equals 114025.08552 milliroentgens. This means to convert sieverts to milliroentgens, you multiply by 114025.08552.
Formula
Step-by-Step Example
Convert 5 Sv to milliroentgens:
We need to convert sieverts to milliroentgens
Since 1 Sv = 114025.08552 mR, multiply by 114025.08552
5 × 114025.08552 = 570125.42759
5 Sv = 570125.42759 mR

About These Units
Sievert (Sv)
The sievert (Sv) is the SI unit of equivalent dose, measuring biological effect of radiation exposure. Accounts for radiation type via quality factors. 1 Sv = significant health risk, 4-5 Sv = 50% fatality (LD50). Acute exposure above 0.5 Sv causes radiation sickness.
Milliroentgen (mR)
A milliroentgen (mR) equals 0.001 roentgen. Radiation survey meters often display mR/h for monitoring X-ray and gamma fields. Natural background: 10-20 mR/year. Typical survey meter range: 0-1000 mR/h.
