How it is calculated
Converted value = original value × source factor / target factor
Worked example
100 rad = 1 Gy.
Things to check
- The gray measures absorbed energy per mass; 1 Gy equals 100 rad. The calculation does not establish biological effect or a treatment dose.
- Rounding is applied only to displayed results. Very small or very large values may appear in scientific notation.
