Because the relationship is a simple proportion, one multiplication does the whole job. The table further down gives pre-computed values for the amounts people look up most often, and the result panel also reports the reverse conversion so you can check the figure both ways.
The formula
hectares- The amount you are converting, measured in hectares
100- The exact number of ares in one hectare
ares- The converted result
How it works, step by step

- The result is displayed in ares, rounded for readability.
- The unrounded value and the reverse conversion appear underneath so you can verify it.
Worked examples
Converting 5 hectares
Multiply 5 by 100. That gives 500 ares. A quick sanity check: one hectare is larger than one are, so the number should get bigger — and it does.
Converting 72 hectares
72 × 100 = 7,200 ares. Working backwards, 7,200 ÷ 100 returns 72 hectares, which confirms the factor is applied the right way round.
