How to use
- Fill in Quantity, Value, From, To for Doseunit.
- To match “2 gray to rad”, enter Quantity absorbed; Value 2; From Gy; To rad.
- Press Convert dose unit. The summary line should be “Doseunit: 200 rad”.
- Read every line under “Doseunit: 200 rad” before you copy the Doseunit result.
- Press Copy for the whole Doseunit result, or Reset to restore “2 gray to rad”.
- For the second check, “50 rem to sievert”, the summary should be “Doseunit: 0.5 sievert”.
Formula / how it works
Example “2 gray to rad” sets Quantity = absorbed; Value = 2; From = Gy; To = rad.
Doseunit returns this exact text:
Doseunit: 200 rad
2 gray → rad within absorbed dose. 1 rad = 0.01 gray and 1 rem = 0.01 sievert.
Gray is not converted to sievert here. That step needs a radiation weighting factor this page does not assume.
1 gray = 100 rad.
Example “50 rem to sievert” sets Quantity = equivalent; Value = 50; From = rem; To = Sv.
Doseunit returns this exact text:
Doseunit: 0.5 sievert
50 rem → sievert within equivalent dose. 1 rad = 0.01 gray and 1 rem = 0.01 sievert.
Gray is not converted to sievert here. That step needs a radiation weighting factor this page does not assume.
1 sievert = 100 rem.
Doseunit vocabulary for this page: gray, rad, sievert, rem, dose, doseunit.
Doseunit pass 1 (“50 rem to sievert”) prints:
Doseunit: 0.5 sievert
50 rem → sievert within equivalent dose. 1 rad = 0.01 gray and 1 rem = 0.01 sievert.
Gray is not converted to sievert here. That step needs a radiation weighting factor this page does not assume.
The words for this pass are gray, rad, sievert, rem, dose, doseunit.
Doseunit pass 2 (“2 gray to rad”) prints:
Doseunit: 200 rad
2 gray → rad within absorbed dose. 1 rad = 0.01 gray and 1 rem = 0.01 sievert.
Gray is not converted to sievert here. That step needs a radiation weighting factor this page does not assume.
The words for this pass are gray, rad, sievert, rem, dose, doseunit.
Worked examples
2 gray to rad
Inputs: Quantity: absorbed | Value: 2 | From: Gy | To: rad
Set Quantity absorbed, then Value 2, then From Gy, then To rad. Press Convert dose unit. The Doseunit summary should read “Doseunit: 200 rad”.
Result: Doseunit: 200 rad
2 gray → rad within absorbed dose. 1 rad = 0.01 gray and 1 rem = 0.01 sievert.
Gray is not converted to sievert here. That step needs a radiation weighting factor this page does not assume.
1 gray = 100 rad.
50 rem to sievert
Inputs: Quantity: equivalent | Value: 50 | From: rem | To: Sv
Set Quantity equivalent, then Value 50, then From rem, then To Sv. Press Convert dose unit. The Doseunit summary should read “Doseunit: 0.5 sievert”.
Result: Doseunit: 0.5 sievert
50 rem → sievert within equivalent dose. 1 rad = 0.01 gray and 1 rem = 0.01 sievert.
Gray is not converted to sievert here. That step needs a radiation weighting factor this page does not assume.
1 sievert = 100 rem.
Use cases
- Check “Doseunit: 200 rad” before trusting a new Doseunit input.
- Check “Doseunit: 0.5 sievert” as the second Doseunit case.
- 1 gray = 100 rad.
- 1 sievert = 100 rem.
Tips & limitations
- “2 gray to rad”: 1 gray = 100 rad.
- “50 rem to sievert”: 1 sievert = 100 rem.
- Doseunit fields: Quantity, Value, From, To.
- The Doseunit summary for the opening example is “Doseunit: 200 rad”.
