Convert Terabecquerels to Rutherfords (TBq to Rd)
1 terabecquerel (TBq) = 1000000 rutherfords (Rd). 1 Rd = 0.000001 TBq. Example: 15 TBq = 15 × 1000000 = 15000000 Rd.

How to Convert Terabecquerel to Rutherford
- 1 TBq = 1000000 Rd
- 1 Rd = 0.000001 TBq
- Example: convert 15 TBq to Rd: 15 TBq = 15 × 1000000 Rd = 15000000 Rd
Formula
Rd = TBq × 1000000
Derivation from SI units:
- 1 TBq = 10¹² Bq.
- 1 Rd = 10⁶ Bq (obsolete).
- 1 TBq = 1000000000000 Bq ÷ 1000000 Bq per Rd = 1000000 Rd
Both units are defined exactly, so the factor is exact. Terabecquerel definition: terabecquerel; Rutherford definition: rutherford.
Worked examples
- A reading of 2 TBq converts to 2000000 Rd.
2 TBq × 1000000 = 2000000 Rd - A value of 20 TBq is 20000000 Rd.
20 TBq × 1000000 = 20000000 Rd

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