20 ly = 1.8922e+20 mm
Full precision:1.8922e+20 mm
Step-by-Step Solution
To convert 20 light years to millimeters, we multiply by 9.461e+18 because one light year equals exactly 9.461e+18 millimeters.
1 light year = 9.461e+18 millimeters
Since each light year contains 9.461e+18 millimeters, we multiply our value by this factor:
20 × 9.461e+18 = 1.8922e+20 millimeters
So 20 light years = 1.8922e+20 millimeters.
Quick check: 1.8922e+20 ÷ 9.461e+18 = 20 light years
