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.
Public interfaces
Machine access
Conversions in this hub are represented by the canonical radiation-activity family and its registered source and target units.
Its 20 published directions use the same canonical engine through the website, JSON API, OpenAPI and WebMCP.
API & Agent documentationExplanation
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.
Open a family hub to reach leaf pages with direct answers, calculator output, and reverse links built on the same constants.
Questions & answers
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.
