Convert Megabecquerels to Terabecquerels (MBq to TBq)
1 megabecquerel (MBq) = 0.000001 terabecquerels (TBq). 1 TBq = 1000000 MBq. Example: 15 MBq = 15 × 0.000001 = 0.000015 TBq.

How to Convert Megabecquerel to Terabecquerel
- 1 MBq = 0.000001 TBq
- 1 TBq = 1000000 MBq
- Example: convert 15 MBq to TBq: 15 MBq = 15 × 0.000001 TBq = 0.000015 TBq
Formula
TBq = MBq ÷ 1000000
Derivation from SI units:
- 1 MBq = 10⁶ Bq.
- 1 TBq = 10¹² Bq.
- 1 MBq = 1000000 Bq ÷ 1000000000000 Bq per TBq = 0.000001 TBq
Both units are defined exactly, so the factor is exact. Megabecquerel definition: megabecquerel; Terabecquerel definition: terabecquerel.
Worked examples
- A reading of 370 MBq converts to 0.00037 TBq.
370 MBq × 0.000001 = 0.00037 TBq - A value of 740 MBq is 0.00074 TBq.
740 MBq × 0.000001 = 0.00074 TBq

Where it's used
Megabecquerels are used for PET and SPECT doses (e.g. 370 MBq of F-18 FDG), 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 megabecquerel?
1 MBq = 0.000001 TBq.
How do I convert megabecquerels to terabecquerels?
Multiply the value in MBq by 0.000001, or divide it by 1000000. For example, 15 MBq × 0.000001 = 0.000015 TBq.
Is the MBq to TBq conversion exact?
Yes. Both units are defined exactly, and 1 MBq is exactly 0.000001 TBq.
