In 2003, Guyana switched to the metric system as the legal measurement system instead of the imperial system.
The Guyana National Bureau of standards has set out to transform Guyana from using the imperial system of measurement to the Metric System. On Wednesday, January 01, 2003 an Order number four (4) of 2002 came in to effect making the metric system, the legal measurement system in Guyana.
The GNBS hopes to achieve this objective through the provision of public education and technical support to the various stakeholders identified under the following sectors:
The Metrication Division, which is responsible for the educational aspect of the programme, is ably assisted by the National Metrication Committee, which meets on the last Tuesday of every month. There is also a legal sub-sector committee which meets on the second Thursday of every month to effect necessary changes to existing legislations, which are still in imperial units. This work will continue until the objective of the programme is met.
Our primary focus at this time is on the four (4) commonly used units for: mass, length and distances, capacity and cubic Measurements.
The Guyana National Bureau of Standards facilitates the availability of metric measuring devices through its Weights and Measures programme. This programme mandates the verification and calibration of measuring devices twice yearly.
