Convert Rutherfords to Terabecquerels (Rd to TBq)
1 rutherford (Rd) = 0.000001 terabecquerels (TBq). 1 TBq = 1000000 Rd. Example: 15 Rd = 15 × 0.000001 = 0.000015 TBq.

How to Convert Rutherford to Terabecquerel
- 1 Rd = 0.000001 TBq
- 1 TBq = 1000000 Rd
- Example: convert 15 Rd to TBq: 15 Rd = 15 × 0.000001 TBq = 0.000015 TBq
Formula
TBq = Rd ÷ 1000000
Derivation from SI units:
- 1 Rd = 10⁶ Bq (obsolete).
- 1 TBq = 10¹² Bq.
- 1 Rd = 1000000 Bq ÷ 1000000000000 Bq per TBq = 0.000001 TBq
Both units are defined exactly, so the factor is exact. Rutherford definition: rutherford; Terabecquerel definition: terabecquerel.
Worked examples
- A reading of 2 Rd converts to 0.000002 TBq.
2 Rd × 0.000001 = 0.000002 TBq - A value of 20 Rd is 0.00002 TBq.
20 Rd × 0.000001 = 0.00002 TBq

Where it's used
Rutherfords are used for older nuclear physics literature, while terabecquerels appear in cobalt-60 and iridium-192 sources. Both measure activity of a radioactive source, so the conversion is a fixed factor.

Frequently asked questions
How many terabecquerels are in 1 rutherford?
1 Rd = 0.000001 TBq.
How do I convert rutherfords to terabecquerels?
Multiply the value in Rd by 0.000001, or divide it by 1000000. For example, 15 Rd × 0.000001 = 0.000015 TBq.
Is the Rd to TBq conversion exact?
Yes. Both units are defined exactly, and 1 Rd is exactly 0.000001 TBq.
