Convert Rutherfords to Gigabecquerels (Rd to GBq)
1 rutherford (Rd) = 0.001 gigabecquerels (GBq). 1 GBq = 1000 Rd. Example: 15 Rd = 15 × 0.001 = 0.015 GBq.

How to Convert Rutherford to Gigabecquerel
- 1 Rd = 0.001 GBq
- 1 GBq = 1000 Rd
- Example: convert 15 Rd to GBq: 15 Rd = 15 × 0.001 GBq = 0.015 GBq
Formula
GBq = Rd ÷ 1000
Derivation from SI units:
- 1 Rd = 10⁶ Bq (obsolete).
- 1 GBq = 10⁹ Bq.
- 1 Rd = 1000000 Bq ÷ 1000000000 Bq per GBq = 0.001 GBq
Both units are defined exactly, so the factor is exact. Rutherford definition: rutherford; Gigabecquerel definition: gigabecquerel.
Worked examples
- A reading of 2 Rd converts to 0.002 GBq.
2 Rd × 0.001 = 0.002 GBq - A value of 20 Rd is 0.02 GBq.
20 Rd × 0.001 = 0.02 GBq

Where it's used
Rutherfords are used for older nuclear physics literature, while gigabecquerels appear in radioiodine therapy (1–7 GBq). Both measure activity of a radioactive source, so the conversion is a fixed factor.

Frequently asked questions
How many gigabecquerels are in 1 rutherford?
1 Rd = 0.001 GBq.
How do I convert rutherfords to gigabecquerels?
Multiply the value in Rd by 0.001, or divide it by 1000. For example, 15 Rd × 0.001 = 0.015 GBq.
Is the Rd to GBq conversion exact?
Yes. Both units are defined exactly, and 1 Rd is exactly 0.001 GBq.
