CPM to mSv/h Calculator
Convert CPM (radiation counts per minute) to mSv/h dose rate using your detector’s calibration factor. Two-way conversion, copyable summary, and optional AI insights.
This page assumes CPM = radiation counts per minute and mSv/h = millisievert per hour (dose rate). The conversion depends on a calibration factor (CPM per mSv/h) for your specific detector/setup.
Example presets
Use the factor from your detector manual or calibration. Higher factor means lower mSv/h for the same CPM.

Formula
mSv/h = CPM / factor
Assumptions
This is an estimate using your factor (CPM per mSv/h). The factor is detector- and context-specific (energy response, geometry, distance, shielding, settings). Do not treat this as a safety decision. CPM here means radiation counts per minute, not marketing CPM. mSv/h is a dose-rate unit (not total dose mSv).

Features
Two-way conversion
Convert CPM to mSv/h or reverse-convert mSv/h to CPM on the same page.
Calibration-factor driven
Uses Factor = CPM per mSv/h so you don’t rely on misleading “universal” constants.
Copyable summary
Copy mode, inputs, factor, result, formula, and key assumptions for sharing.
Optional AI insights
Get practical interpretation and next steps (with graceful fallback when AI is unavailable).
How it works
