According to the 2010 CIA Factbook, Myanmar is one of three countries that have not adopted the International System of Units (SI) metric system as their official system of weights and measures. However, in June 2011, the Burmese government's Ministry of Commerce began discussing proposals to reform the measurement system in Burma and adopt the metric system used by most of its trading partners, and in October 2013, Pwint San, Deputy Minister for Commerce, announced that the country was preparing to adopt the metric system.
Burmese government web pages in English use imperial and metric units inconsistently. For instance, the Ministry of Construction uses miles to describe the length of roads and square feet for the size of houses, but square kilometres for the total land area of new town developments in Yangon City. The Ministry of Agriculture uses acres for land areas. The Ministry of Foreign Affairs uses kilometres (with mile equivalents in parentheses) to describe the dimensions of the country.

Adoption of SI (metric) system
Examples of metrication in Myanmar include weather forecasts by the Department of Meteorology and Hydrology being given with temperatures in Celsius. Petrol in Myanmar is sold with prices in Burmese kyat per litre (K/L). Speed limits in Myanmar are given by law in kilometres per hour (km/h).
