Convert Kilobecquerels to Rutherfords (kBq to Rd)
1 kilobecquerel (kBq) = 0.001 rutherfords (Rd). 1 Rd = 1000 kBq. Example: 15 kBq = 15 × 0.001 = 0.015 Rd.

How to Convert Kilobecquerel to Rutherford
- 1 kBq = 0.001 Rd
- 1 Rd = 1000 kBq
- Example: convert 15 kBq to Rd: 15 kBq = 15 × 0.001 Rd = 0.015 Rd
Formula
Rd = kBq ÷ 1000
Derivation from SI units:
- 1 kBq = 10³ Bq.
- 1 Rd = 10⁶ Bq (obsolete).
- 1 kBq = 1000 Bq ÷ 1000000 Bq per Rd = 0.001 Rd
Both units are defined exactly, so the factor is exact. Kilobecquerel definition: kilobecquerel; Rutherford definition: rutherford.
Worked examples
- A reading of 2 kBq converts to 0.002 Rd.
2 kBq × 0.001 = 0.002 Rd - A value of 20 kBq is 0.02 Rd.
20 kBq × 0.001 = 0.02 Rd

Where it's used
Kilobecquerels are used for laboratory sources and calibration standards, while rutherfords appear in older nuclear physics literature. Both measure activity of a radioactive source, so the conversion is a fixed factor.

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