Imperial/American to Metric (Fahrenheit to Celsius/centigrade) conversions for length and area, air, body and oven temperatures, and US to UK to Euro clothing conversion tables...
Officially Thailand uses the metric system of measurement for units and weights. However, distance, size, area and weight are frequently quoted in either Imperial (pounds, yards, feet and inches) or metric (kilogrammes, metres and centimetres).
Area - with reference to property, land and building - is frequently measured in Rai, Ngan and Wah.
Temperature is measured in degrees Celsius.
