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

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

Where it's used
Rutherfords are used for older nuclear physics literature, while megabecquerels appear in PET and SPECT doses (e.g. 370 MBq of F-18 FDG). Both measure activity of a radioactive source, so the conversion is a fixed factor.

Frequently asked questions
How many megabecquerels are in 1 rutherford?
1 Rd = 1 MBq.
How do I convert rutherfords to megabecquerels?
Multiply the value in Rd by 1. For example, 15 Rd × 1 = 15 MBq.
Is the Rd to MBq conversion exact?
Yes. Both units are defined exactly, and 1 Rd is exactly 1 MBq.
