## How it works

1 hectare = 10,000 m² exactly; 1 acre = 4,046.86 m² (43,560 ft²). So acres = hectares × 10,000 ÷ 4,046.86 ≈ hectares × 2.47105, and hectares = acres × 0.404686.

## Worked example

A 2.5-hectare orchard: 2.5 × 2.47105 = 6.178 acres. In the other direction, a 10-acre parcel is 10 × 0.404686 = 4.047 hectares.

## Assumptions

- Acre uses the US survey definition of 4,046.86 m² (43,560 ft²); results may differ in the last decimal from converters that round to 4,047.
- Conversions are exact ratios — no terrain or shape corrections apply.
- The input value is accepted in hectares, acres, or square metres via the unit selector.

## Common questions

### How many acres is 1 hectare?

2.471 acres (1 ha = 10,000 m², 1 acre = 4,046.86 m²). Multiply hectares by 2.47105.

### How many hectares is 1 acre?

0.4047 hectares. Multiply acres by 0.404686 — or divide acres by 2.47105.

### Which is bigger, a hectare or an acre?

A hectare — about 2.47 times bigger. A hectare is a 100 m × 100 m square; an acre is about 208.7 ft × 208.7 ft.

### Is an acre metric or imperial?

Imperial/US customary: 43,560 square feet, originally the area a yoke of oxen could plough in a day.

### How big is a hectare in football fields?

About 1.4 FIFA-standard pitches (0.714 ha each), or 2.47 acres.

### Why do I get slightly different values on other converters?

Many round the acre to 4,047 m² or the factor to 2.47. This tool uses the exact survey definition (4,046.86 m²) — the difference only matters at large scales.

### Does the tool convert the other direction too?

Yes — pick the unit you are converting from and enter the value; hectares, acres, and square metres all work in either direction.
