In Cambodia, ? – 20th century, a unit of length. In the 20th century = 50 centimeters. (UN, 1966) Before metrification, 41 cm.

Using measurements of 200 dimensions of the temple of Angor Wat (built in the 12th century), researchers calculated that the value most nearly dividing the dimensions a whole number of times is 43.545 centimeters, which makes that number a likely estimate for the magnitude of the hat at the time of construction.1

As the measurements of the temple were made to the nearest millimeter, the last two digits of the calculated value are not meaningful.
