Convert Rad to Nanogray

Input the number of rads you want to convert to nanograys.

1 rad (rads) = 10000000 nGy (nanograys)

How to Convert Rads to Nanograys

The rad and nanogray are both units of radiation dose. By definition, 1 rad equals exactly 10000000 nanograys. This means to convert rads to nanograys, you multiply by 10000000.

Formula

nanograys = rads × 10000000

Step-by-Step Example

Convert 5 rad to nanograys:

1
Convert 5 rad to nanograys

We need to convert rads to nanograys

2
Apply the formula

Since 1 rad = 10000000 nGy, multiply by 10000000

5 × 10000000 = 50000000

Answer

5 rad = 50000000 nGy

About These Units

Rad (rad)

The rad (Radiation Absorbed Dose) is the traditional unit of absorbed dose. One gray = 100 rads exactly. One rad = 100 ergs/gram = 0.01 J/kg. Still used in US medical and nuclear industries. One rad = one centigray = one rem for gamma/X-rays.

Nanogray (nGy)

A nanogray (nGy) equals 10⁻⁹ grays. Used in background radiation measurements and environmental monitoring. Natural background dose rate: 50-200 nGy/h from cosmic rays and terrestrial sources. Sensitive dosimeters measure in nGy.
