Step-by-Step Solution
To convert 0.25 kilometers to nanometers, we multiply by 1e+12 because one kilometer equals exactly 1e+12 nanometers.
1 kilometer = 1e+12 nanometers
Since each kilometer contains 1e+12 nanometers, we multiply our value by this factor:
0.25 × 1e+12 = 2.5e+11 nanometers
So 0.25 kilometers = 2.5e+11 nanometers.
Quick check: 2.5e+11 ÷ 1e+12 = 0.25 kilometers
