Rutherford quick reference
| Rutherford | Gigabecquerel | Curie | Becquerel |
|---|---|---|---|
| 1 Rd | = 0.001 GBq | ≈ 0.00002702702703 Ci | = 1000000 Bq |
| 10 Rd | = 0.01 GBq | ≈ 0.0002702702703 Ci | = 10000000 Bq |
| 100 Rd | = 0.1 GBq | ≈ 0.002702702703 Ci | = 100000000 Bq |
| 1000 Rd | = 1 GBq | ≈ 0.02702702703 Ci | = 1000000000 Bq |
Where the rutherford fits
The next smaller radioactivity unit is the microcurie (µCi). 1 Rd ≈ 27.02702703 µCi, and 1 µCi = 0.037 Rd.
The next larger radioactivity unit is the millicurie (mCi). 1 Rd ≈ 0.02702702703 mCi, and 1 mCi = 37 Rd.
