Convert are to hectare easily.

If you've ever dealt with land measurements in Europe or read agricultural reports, you've probably encountered ares and hectares. These two units are like cousins in the metric system’s area family—one modest in size, the other grand enough to cover entire fields. But how do you move between them without getting tangled in decimal points? Let’s break it down step by step, with real-life examples and a dash of history to keep things lively.

Unit definitions

What is a are (a)?

The are (symbol: a) is a metric unit of area equal to 100 square meters. Think of it as a 10m x 10m square, roughly the size of a small studio apartment. It’s commonly used for measuring smaller land plots, like gardens or urban lots. Despite its practicality, it’s been largely overshadowed by the hectare in many contexts.

What is a hectare (ha)?

A hectare (symbol: ha) is the bigger sibling, covering 10,000 square meters or 100 ares. Visualize a square measuring 100m per side—that’s a hectare. It’s the go-to unit for agriculture, forestry, and land planning. When someone says a farm is 50 hectares, they’re talking about 500,000 square meters of land.

Conversion formula

Converting ares to hectares is straightforward:
Hectares = Ares × 0.01
Since 1 are = 0.01 hectares, you’re essentially moving the decimal point two places to the left. For hectares to ares, reverse it:
Ares = Hectares × 100

Example calculations

1. Converting 45 ares to hectares:
   45 a × 0.01 = 0.45 ha
   That’s like turning a 45-are vineyard into its hectare equivalent for a wine region map.
2. Converting 12.3 hectares to ares:
   12.3 ha × 100 = 1,230 a
   Useful when a land surveyor needs to detail a 12.3-ha forest in smaller units.

Hectare to are

From revolutionary France to modern farms

The are and hectare were born during the French Revolution’s metric system overhaul in the 1790s. Designed to simplify measurements, the are (from the Latin "area") became a standard for land. But as agriculture scaled up, the hectare offered a benifit making large-area calculations less cumbersome. Today the hectare is a global staple, while the are lingers in specific regions like Switzerland and Norway for smaller plots.

Interesting facts

1. Olympic-sized comparison: One hectare is roughly 1.4 soccer fields.
2. Global usage: France officially retired the are in 1960, but it’s still taught in schools.
3. Metric flexibility: Ares can be converted to square meters by multiplying by 100.
4. Historical roots: The hectare was originally called the "hectoare" before shortening.
5. Urban planning: City parks in Europe are sometimes measured in ares for precision.
