Convert Microcuries to Terabecquerels (µCi to TBq)
1 microcurie (µCi) = 3.7 × 10⁻⁸ terabecquerels (TBq). 1 TBq = 27027027.03 µCi. Example: 15 µCi = 15 × 3.7 × 10⁻⁸ = 5.55 × 10⁻⁷ TBq.

How to Convert Microcurie to Terabecquerel
- 1 µCi = 3.7 × 10⁻⁸ TBq
- 1 TBq = 27027027.03 µCi
- Example: convert 15 µCi to TBq: 15 µCi = 15 × 3.7 × 10⁻⁸ TBq = 5.55 × 10⁻⁷ TBq
Formula
TBq = µCi × 3.7 × 10⁻⁸
or TBq = µCi ÷ 27027027.02703
Derivation from SI units:
- 1 µCi = 3.7 × 10⁴ Bq = 37 kBq.
- 1 TBq = 10¹² Bq.
- 1 µCi = 37000 Bq ÷ 1000000000000 Bq per TBq = 3.7 × 10⁻⁸ TBq
Both units are defined exactly, so the factor is exact. Microcurie definition: microcurie; Terabecquerel definition: terabecquerel.
Worked examples
- A reading of 2 µCi converts to 7.4 × 10⁻⁸ TBq.
2 µCi × 3.7 × 10⁻⁸ = 7.4 × 10⁻⁸ TBq - A value of 20 µCi is 7.4 × 10⁻⁷ TBq.
20 µCi × 3.7 × 10⁻⁸ = 7.4 × 10⁻⁷ TBq

Where it's used
Microcuries are used for check and calibration sources, while terabecquerels appear in cobalt-60 and iridium-192 sources. Both measure activity of a radioactive source, so the conversion is a fixed factor.
