Millisieverts per hour to microsieverts per hour
Type a value in mSv/h to get it in µSv/h instantly.
100µSv/h
That's 5× as strong as a hotspot in Chernobyl’s Red Forest — nothing on our list beats it. A whole year in it would be about 876.6 mSv, against a world average of 2.4.
What it means
How much radiation is that?
Yearly figures assume constant exposure for all 8,766 hours of a year, which is how limits are written but rarely how life works.
The math
How to convert mSv/h to µSv/h
To convert millisieverts per hour to microsieverts per hour, multiply by 1,000.
Example: 0.1 mSv/h × 1,000 = 100 µSv/h.
In the other direction, 1 µSv/h = 0.001 mSv/h.
