Formula
Formula
rad = krad × 1000
Multiply any value in kilorads by 1000 to obtain the value in rad (radiation absorbed dose).
Worked example
Convert 1 krad to rad.
- 01Start with 1 krad.
- 02Multiply by the conversion factor: 1 × 1000 = 1000 rad.
Result1 krad = 1000 rad

FAQ
What is the conversion factor from krad to rad?
1 krad equals 1000 rad. To convert, multiply the value in kilorads by 1000.
How do I convert 1 krad to rad?
1 krad = 1000 rad. For any value, multiply by 1000.
How do I convert rad back to krad?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 rad = 0.001 krad.
When would I need to convert kilorad to rad (radiation absorbed dose)?
Radiation absorbed-dose conversions between krad and rad are used in radiological protection, medical physics, and nuclear-industry health physics. Gray (Gy) is the SI standard; rad remains common in older US health-physics documentation (1 Gy = 100 rad).
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
