Step-by-Step Solution
To convert 1 milligrays to roentgens, we divide by 8.77 because one roentgen equals exactly 8.77 milligrays.
1 roentgen = 8.77 milligrays
Since there are 8.77 milligrays in every roentgen, we divide our value by this factor:
1 ÷ 8.77 = 0.11403 roentgens
So 1 milligrays = 0.11403 roentgens.
Quick check: 0.11403 × 8.77 = 1 milligrays
Example Conversions
Example 1: 1 mGy = 0.11403 R
1 ÷ 8.77 = 0.11403
1 ÷ 8.77 = 0.11403
Example 2: 5 mGy = 0.57013 R
5 ÷ 8.77 = 0.57013
5 ÷ 8.77 = 0.57013
Example 3: 10 mGy = 1.1403 R
10 ÷ 8.77 = 1.1403
10 ÷ 8.77 = 1.1403
