Terabecquerel quick reference
| Terabecquerel | Gigabecquerel | Curie | Becquerel |
|---|---|---|---|
| 1 TBq | = 1000 GBq | ≈ 27.02702703 Ci | = 1000000000000 Bq |
| 10 TBq | = 10000 GBq | ≈ 270.2702703 Ci | = 10000000000000 Bq |
| 100 TBq | = 100000 GBq | ≈ 2702.702703 Ci | = 100000000000000 Bq |
| 1000 TBq | = 1000000 GBq | ≈ 27027.02703 Ci | = 1e+15 Bq |
Where the terabecquerel fits
The next smaller radioactivity unit is the curie (Ci). 1 TBq ≈ 27.02702703 Ci, and 1 Ci = 0.037 TBq.
