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