Questions & answers

Frequently Asked Questions

What exact relationship does this Rads to Grays page use for rad and gray?

This route uses the exact relationship 1 rad = 0.01 gray, so gray-based SI values and legacy rad values stay aligned across the page.

When would I convert rads to grays?

Use this route when restating absorbed-dose values across radiology, dosimetry, shielding, and laboratory reporting scales.

How do I reverse Rads to Grays?

Use the mirror Grays to Rads route; it applies the inverse relationship with the same absorbed-dose assumptions.
