Converting the other way: hectares to square centimeters
square centimeters = hectares × 100,000,000. So 1.2e-7 hectares is back to 12 square centimeters; one hectare is 100,000,000 square centimeters. See the hectares to square centimeters table.
Quick estimate in your head
For a rough answer, multiply by about 1e-8: 12 × 1e-8 ≈ 1.2e-7 ha, against the exact 1.2e-7 ha (0.0% out). Good enough to check that a calculated result is sensible.
Common mistakes
The usual slip is using the factor the wrong way round. A square centimeter is smaller than a hectare, so the number of hectares must come out smaller than the number of square centimeters. If your answer goes the other way, divide instead of multiplying.
