How do I convert micrograys to millirads by hand?

Use mrad = µGy × 0.1. The step-by-step panel shows the same calculation with your own numbers substituted in.

Is the answer exact or rounded?

The calculation itself uses the full stored precision of the defined factor. Only the displayed figure is rounded, and the page also shows a shorter everyday value beside the full one.

Can I check the conversion the other way round?

Yes. The result panel converts the answer straight back into your original unit so you can confirm nothing was lost.

Can I download the result?

Yes — the PDF button produces a branded report with your input, the answer, the formula and the full working.

What this calculator does

Converts a measurement given in micrograys into millirads using the defined conversion factor.

What your result means

The same quantity expressed in mrad instead of µGy. Nothing about the measurement itself changes.

Formula and working

mrad = µGy × 0.1

1
Start with your value
100 µGy
2
Convert to gray
100 × 0.000001 = 0.0001 Gy
3
Convert into millirads
0.0001 ÷ 0.00001 = 10 mrad
4
Result
100 µGy = 10 mrad

Frequently asked questions

Symbols and assumptions

µGy: Input unit — microgray
mrad: Output unit — millirad
Gy: Base unit used internally for absorbed radiation dose

• Both units measure absorbed radiation dose, so the physical quantity is unchanged by the conversion.
• The relationship is exactly linear: 1 µGy = 0.1 mrad.
• Values are converted through the SI base unit for this quantity rather than pair by pair.

• A unit conversion changes how a number is expressed, not how it was measured — the answer can never be more accurate than the value entered.
• Displayed figures are rounded for readability; the full stored precision of the mrad value is used in every onward calculation.
