About these units
Chō (area) (chō)
3,000 tsubo, about 9,917 m² (roughly one hectare; 2.45 acres). Used for farmland in Japan.
Almost exactly a hectare, the cho is the largest of the everyday Japanese land units. It is 3,000 tsubo, or 1,200,000/121 square metres, about 9,917, which is 0.9917 hectare or roughly 2.45 acres. It is also 100 se or 10 tan, and when no fractional part follows it is often written cho-bu.
Because it is so near a hectare, it is a convenient mental bridge for anyone moving between traditional and metric figures. In Japan it has been used for farmland, and it sits at the top of the tsubo, se and tan ladder.
The name is shared with a unit of length, so the area sense needs to be stated. The area figure used here follows from the 10/33 metre shaku fixed by the 1891 Meiji law, and the 1951 Measurements Law took the traditional units out of official use from 1959.
1 chō (area) = 9,917.355372 square meters (approximately).

Square Yard (yd²)
9 square feet (0.8361 m²). Used for carpet, turf and land in the UK and India (where it is called a gaj).
Branches and rods lie behind this unit. The word yard comes from Old English gerd or gyrd, meaning a staff or measuring rod, and it first appears in the late seventh-century laws of Ine of Wessex, where a yard of land was a tax unit. Where its length came from is uncertain: pacing, the cubit and the arm of King Henry I have all been suggested. A square yard is simply a square of that length on each side.
After the 1959 agreement among six countries fixed the yard at exactly 0.9144 meter, the square yard became exactly 9 square feet, 1,296 square inches or about 0.836 m². It is used across the English-speaking world, notably in the United States, United Kingdom, Canada, India and Pakistan. In northern India it is called a gaj, and in Pakistan a gaz, and house plots there are often quoted in it. In the US and UK the yard, divided into eighths, is also how cloth is bought, so the square yard suits flooring and fabric in the same breath.
1 square yard = 0.83612736 square meters (exactly).
