Convert Megabecquerels to Rutherfords (MBq to Rd)
1 megabecquerel (MBq) = 1 rutherford (Rd). 1 Rd = 1 MBq. Example: 15 MBq = 15 × 1 = 15 Rd.

How to Convert Megabecquerel to Rutherford
- 1 MBq = 1 Rd
- 1 Rd = 1 MBq
- Example: convert 15 MBq to Rd: 15 MBq = 15 × 1 Rd = 15 Rd
Formula
Rd = MBq × 1
Derivation from SI units:
- 1 MBq = 10⁶ Bq.
- 1 Rd = 10⁶ Bq (obsolete).
- 1 MBq = 1000000 Bq ÷ 1000000 Bq per Rd = 1 Rd
Both units are defined exactly, so the factor is exact. Megabecquerel definition: megabecquerel; Rutherford definition: rutherford.
Worked examples
- A reading of 370 MBq converts to 370 Rd.
370 MBq × 1 = 370 Rd - A value of 740 MBq is 740 Rd.
740 MBq × 1 = 740 Rd

Where it's used
Megabecquerels are used for PET and SPECT doses (e.g. 370 MBq of F-18 FDG), 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 megabecquerel?
1 MBq = 1 Rd.
How do I convert megabecquerels to rutherfords?
Multiply the value in MBq by 1. For example, 15 MBq × 1 = 15 Rd.
Is the MBq to Rd conversion exact?
Yes. Both units are defined exactly, and 1 MBq is exactly 1 Rd.
