Radiation Activity Converters
Convert between Bq, kBq, MBq, GBq, and Ci using exact becquerel-based radiation activity relationships. This hub keeps SI and curie routes aligned on dedicated mirror pages.
Scope & Verification
This hub groups related converter families so you can move from the category level to exact routes with one clear basis per page.
- Families are split so exact-factor, profile-based, density-based, and estimate-style pages do not collapse into one generic answer.
- Leaf pages keep calculator, common values, FAQ, and reverse routes aligned to the same assumption.
- Methodology and verification pages document how those assumptions are chosen and checked.
Explanation
Radiation activity measures radioactive decays per second. This hub normalizes every route through becquerels (Bq), so SI multiples and curie-based pages stay exact, multiplicative, and reversible on the matching mirror page.
Radiation Activity converters are grouped into directional families so each leaf keeps one stable conversion model.

Frequently Asked Questions
What is the SI unit of radiation activity?
The SI unit is the becquerel (Bq).
How is curie related to Bq?
Exactly: 1 Ci = 3.7 × 10¹⁰ Bq.
What do kBq, MBq, and GBq mean?
They are decimal SI multiples of becquerels: 10³, 10⁶, and 10⁹ times 1 Bq.
Are radiation activity conversions multiplicative?
Yes. These conversions are purely multiplicative with no offsets.
How do I switch direction?
Open the mirror page for the reverse conversion when you need the same becquerel-based relationship in the opposite direction.
