Convert Gigabecquerels to Rutherfords (GBq to Rd)
1 gigabecquerel (GBq) = 1000 rutherfords (Rd). 1 Rd = 0.001 GBq. Example: 15 GBq = 15 × 1000 = 15000 Rd.

How to Convert Gigabecquerel to Rutherford
- 1 GBq = 1000 Rd
- 1 Rd = 0.001 GBq
- Example: convert 15 GBq to Rd: 15 GBq = 15 × 1000 Rd = 15000 Rd
Formula
Rd = GBq × 1000
Derivation from SI units:
- 1 GBq = 10⁹ Bq.
- 1 Rd = 10⁶ Bq (obsolete).
- 1 GBq = 1000000000 Bq ÷ 1000000 Bq per Rd = 1000 Rd
Both units are defined exactly, so the factor is exact. Gigabecquerel definition: gigabecquerel; Rutherford definition: rutherford.
Worked examples
- A reading of 2 GBq converts to 2000 Rd.
2 GBq × 1000 = 2000 Rd - A value of 20 GBq is 20000 Rd.
20 GBq × 1000 = 20000 Rd

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