Why this tool is useful
Use this converter when a absorbed dose value is supplied in nanograys, while a specification, worksheet or report requires milligrays.

Nanograys to Milligrays Converter
Convert nanograys (nGy) to milligrays (mGy) with a transparent absorbed dose base-unit calculation.
Ready. Your working data stays in this browser.
How it works
The browser multiplies nGy by 1e-09 to reach the shared SI reference, then divides by 0.001 to return mGy. No value leaves the page.
Practical example
Entering 1 nGy returns 1e-06 mGy; the page also shows the exact factors used for an independent check.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
