1 R = 0.877 rem
Full precision:0.877 rem
Step-by-Step Solution
To convert 1 roentgens to rems, we divide by 1.1403 because one rem equals exactly 1.1403 roentgens.
1 rem = 1.1403 roentgens
Since there are 1.1403 roentgens in every rem, we divide our value by this factor:
1 ÷ 1.1403 = 0.877 rems
So 1 roentgens = 0.877 rems.
Quick check: 0.877 × 1.1403 = 1 roentgens
Example Conversions
Example 1: 1 R = 0.877 rem
1 ÷ 1.1403 = 0.877
1 ÷ 1.1403 = 0.877
Example 2: 5 R = 4.385 rem
5 ÷ 1.1403 = 4.385
5 ÷ 1.1403 = 4.385
Example 3: 10 R = 8.77 rem
10 ÷ 1.1403 = 8.77
10 ÷ 1.1403 = 8.77
