The National Measurement and Calibration Center maintains the national kilogram, which is copy No. 93 of the International Kilogram (IPK) made from an alloy of Platinum (90%) and Iridium (10%) with special specifications. Measurements of mass and related quantities have great importance in many of our daily life needs. These measurements are carried out by industry, military, health and civil sectors in various applications with different levels of precision and accuracy. In the department of Mass Measurements, attention was paid to covering the basic needs of industrial and service sectors in the Kingdom of Saudi Arabia. Therefore, it has been structured into 9 specialized laboratories:
