Step-by-Step Solution
To convert 1 millirems to roentgens, we divide by 877 because one roentgen equals exactly 877 millirems.
1 roentgen = 877 millirems
Since there are 877 millirems in every roentgen, we divide our value by this factor:
1 ÷ 877 = 0.00114 roentgens
So 1 millirems = 0.00114 roentgens.
Quick check: 0.00114 × 877 = 1 millirems
Example Conversions
Example 1: 1 mrem = 0.00114 R
1 ÷ 877 = 0.00114
1 ÷ 877 = 0.00114
Example 2: 5 mrem = 0.005701 R
5 ÷ 877 = 0.005701
5 ÷ 877 = 0.005701
Example 3: 10 mrem = 0.011403 R
10 ÷ 877 = 0.011403
10 ÷ 877 = 0.011403
