Formula
Formula
TBq = MBq × 1e-6
Multiply any value in megabecquerels by 1e-6 to obtain the value in terabecquerels.
Worked example
Convert 1.00000e+6 MBq to TBq.
- 01Start with 1.00000e+6 MBq.
- 02Multiply by the conversion factor: 1.00000e+6 × 1e-6 = 1 TBq.
Result1.00000e+6 MBq = 1 TBq

FAQ
What is the conversion factor from MBq to TBq?
1 MBq equals 1e-6 TBq. To convert, multiply the value in megabecquerels by 1e-6.
How do I convert 1 MBq to TBq?
1 MBq = 1e-6 TBq. For any value, multiply by 1e-6.
How do I convert TBq back to MBq?
Divide by the same factor — or equivalently, multiply by 1000000. So 1 TBq = 1.00000e+6 MBq.
When would I need to convert megabecquerel to terabecquerel?
Radioactivity (activity) conversions between MBq and TBq are routine in health physics, nuclear medicine ordering, environmental monitoring, radiopharmacy and reactor/accelerator-source documentation. The becquerel (Bq) is the SI unit; the curie (Ci) is the legacy unit (1 Ci ≡ 3.7×10¹⁰ Bq exactly). This category is strictly activity (decays per second) — it does NOT cover absorbed dose (Gy, rad), dose equivalent (Sv, rem), exposure or dose rate, all of which are different physical quantities and live in separate categories.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
