Numbers and Measurements in Thailand

Last Updated on

For Americans, most of the counting system overall will be strange since the metric system is in use, along with other Thai-specific numbers, counting, and measurements.

American vs. Metrics

  • Dozen eggs --> 10 eggs
  • Dozen anything --> 10 anything
  • paper 8.5" x 11" vs. A4 (210 x 297mm) = 8.27" × 11.69", slightly narrower and longer
  • miles (mi) vs. kilometers/kilometres (km)
  • pounds (p) vs. kilograms (kg)
  • gallons vs. liters/litres
    • note that it is easy to measure everything by weight, especially in the kitchen, as 1 liter of water = 10cm x 10cm x 10cm = 1 kilogram at maximal density (4 degrees centigrade)
  • fahrenheit vs. centigrade
