How to convert millirems to microsieverts
To convert millirems to microsieverts, multiply the amount in millirems by 10. For example, 10 mrem = 100 µSv. To convert in the other direction, divide by the same factor, or use the ⇄ swap button above.
Convert equivalent dose between sieverts and rems. One sievert equals exactly 100 rem; natural background is about 2–3 mSv per year.
