Rems to Microsieverts formula and what each symbol means
µSv = rem × 10,000
| Symbol | Meaning |
|---|---|
| rem | Rem |
| µSv | Microsievert |
Rems to Microsieverts examples
1 rem
1 rem × 10,000 = 10,000 µSv.
10 rem
10 rem × 10,000 = 100,000 µSv.
100 rem
100 rem × 10,000 = 1,000,000 µSv.
Rems compared with Microsieverts
One rem is 10,000 times as large as one µSv, so your number gets bigger when you convert rems to microsieverts and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About rems and microsieverts
Rem (rem): The rem, exactly 0.01 Sv. Microsievert (µSv): Microsievert, 1×10⁻⁶ Sv.
How to calculate Rems to Microsieverts step by step
- Enter the value in rem (the starting unit).
- Multiply by 10,000, because 1 rem = 10,000 µSv.
- The product is the value in µSv. To go back, divide by 10,000 or multiply by 0.0001.

- Dividing when you should multiply: from rem to µSv multiply by 10,000; from µSv to rem divide by 10,000.
Rems to Microsieverts FAQ
How many µSv are in 1 rem?
1 rem equals 10,000 µSv.
How many rem are in 1 µSv?
1 µSv equals 0.0001 rem.
Is 1 rem = 10,000 µSv an exact conversion?
The factor is shown rounded to 7 significant figures (10,000). The calculator above uses more digits.
What is a microsievert (µSv)?
Microsievert, 1×10⁻⁶ Sv.
How can I estimate rems to microsieverts in my head?
One rem is 10,000 times as large as one µSv, so your number gets bigger when you convert rems to microsieverts and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
What is 15 rem in microsieverts?
15 rem = 150,000 µSv (since 15 × 10,000).
What is 75 rem in microsieverts?
75 rem = 750,000 µSv (since 75 × 10,000).
What is 300 rem in microsieverts?
300 rem = 3,000,000 µSv (since 300 × 10,000).
How many decimals should I keep when converting rem to µSv?
Match the precision of your original measurement. For example, 100,000 µSv rounds to 100,000 µSv at 3 significant figures; keep more digits only for engineering or scientific work.
