How the Calculation Works (Linear Scaling)

Formula:

Sievert = Rem / 100

Substitution:1 / 100

Calculated Result:0.01 Sv

Since 1 Sievert = 100 Rems, divide the value in Rems by 100.

Standard Ratio Factor:1 rem = 0.01 Sv

📌 Standard Benchmark Reference Values

100 rem=1 Sv (sievert)

Biological radiation protection dose equivalence (1 rem = 0.01 Sv = 10 mSv).

Exact Ratio

About Rem (rem)

A non-SI unit of equivalent dose standing for "roentgen equivalent man", defined as exactly 0.01 sievert (1 rem = 0.01 Sv = 10 mSv).

History: Introduced in the Manhattan Project era and standardized by the US NRC to quantify biological radiation risk in human tissue.

Common Uses: United States Nuclear Regulatory Commission (NRC) occupational regulations (5 rem/year worker limit), US military radiological doctrine.

About Sievert (Sv)

The SI coherent derived unit of equivalent and effective radiation dose, defined as the absorbed dose in grays multiplied by dimensionless biological radiation weighting factors (wR) and tissue weighting factors (wT) (1 Sv = 1 J/kg).

History: Named in 1979 in honor of Swedish medical physicist Rolf Sievert (1896–1966), founding member of the ICRP.

Common Uses: Radiation protection regulations (ICRP, NRC), occupational radiation worker dose monitoring, nuclear safety emergency thresholds.

❓ Frequently Asked Questions

How many Sieverts are in 1 Rem?

There are exactly 0.01 Sieverts in 1 Rem (1 rem = 0.01 Sv).

What is the formula to convert Rem to Sievert?

The formula is: Sievert = Rem / 100. Since 1 Sievert = 100 Rems, divide the value in Rems by 100.

How do I convert 1 rem to Sv manually?

To convert 1 rem to Sv: apply the formula Sievert = Rem / 100. Substituting gives: 1 / 100 = 0.01 Sv.
