Formula and example

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.
