The hectare is a metric land measurement equivalent to 10,000 square meters. It is commonly used in Europe and the Middle East. The US and UK use acres, which are not equal to hectares. The hectare is often abbreviated as “ha” and the acre is about 40% of a hectare. Converting acres to SI measurements could be difficult due to land surveying and title rights issues. Some countries have renamed the hectare, but the abbreviation remains the same.
For many people who live in places like the US or the UK, the term hectare may not be all that familiar. This is a type of measurement belonging to the International System of Units, also written as SI, which typically refers to an amount of land. The term usually doesn’t have many applications for use outside land surveying and could be comparable to how the US and UK use acres to measure land. It should be noted that an acre is not equal to a hectare, which is 10,000 square meters (107,639.10 square feet).
There are additional measurements beyond this metric land measurement that may not be familiar to all but the most dedicated cartographers, city planners, real estate developers, and mathematicians. Hectare is also considered a square hectometre/hectometre, 100 ares or 10 decaries. Many of these terms aren’t used often, unless it’s about dividing the earth into smaller pieces. Meters could be used instead of hectares, as they are more recognizable.
However, given more than the occasional use of the measure, it’s not a bad idea to know how to appropriately shorten the term. Hectare is usually written as ha and are as a. It also helps those unfamiliar with the term to think about the relative sizing of the acre versus other more familiar measurements.
The standard US acre, for example, would account for about 40% of a hectare, and the UK acre would also be relatively close to this amount. This makes it much easier to view the dimensions. A hectare is about two and a half standard US acres. Of course acres vary in size and two Scottish and Irish acres would be almost the same size as 10,000 square metres.
Given the drive to convert most measurements to metrics in many countries, the question must be asked as to why some countries have stuck to the acre instead of converting acres to SI measurements. This could actually be a monumental task because the earth doesn’t break up into neat square packets. Land surveying could be a nightmare, create questions about title rights, and cost significant amounts of money and time.
On the other hand, many countries use hectares for measurement with ease. It is quite common in much of Europe, many parts of the Middle East and elsewhere. Even though this measure is part of the International System of Units, one confusing aspect is that it may not always have the same name. Several countries have renamed hectare, although the abbreviation may remain the same. However, if people want to measure land in Argentina, they will need to know that hectares and manzana are the same thing, and in Iran, however, land measurements could be counted in jerib.
