The exact conversion ratio — 1.00000e+10 — anchored to SI definitions, not rounded

1. 01Look up the SI factors: 1 square kilometer = 1000000 base units, 1 square centimeter = 0.0001 base units.
2. 02Divide to get the conversion ratio: 1000000 / 0.0001 = 1.00000e+10.
3. 03Multiply by the quantity: 5 × 1.00000e+10 = 5.00000e+10.
4. 04So 5 square kilometers = 5.00000e+10 square centimeters.
