What is Hectare?

The hectare is a unit of area equal to 10,000 square meters, or a square 100 meters on each side. It is the most common unit for reporting agricultural land area worldwide. One hectare is roughly the size of 1.4 soccer fields or 2.47 acres. National parks, vineyards, and urban green spaces are often described in hectares. Although not an official SI unit, the hectare is accepted for use with the SI and is recognized by the International Bureau of Weights and Measures.

What is Jo?

The jo is a Japanese unit of area based on the size of one tatami mat, standardized at 1.62 square meters for real estate purposes by the Japan Fair Trade Council. However, actual tatami dimensions vary by region: the Kyoto-style kyoma is about 1.82 m², the Tokyo-style edoma is about 1.55 m², and the Nagoya-style chukyo-ma is about 1.66 m². In Japanese housing, room sizes are almost always described in jo (for example, "a 6-jo room" or "an 8-jo living room"). This unit provides an intuitive sense of room size that is deeply rooted in Japanese residential culture.
