Weights
Balances
and weights have been used to determine the quantity of matter for more
than 10,000 years.
The modern concept of mass and weight is about 300 years old. Mass is the amount of matter in a body and weight is the force exerted by a body due to gravity. Confusingly the standards of mass are called weights.
Calibrations of mass are carried out by comparing the force exerted by a body with the force exerted by a standard of a higher accuracy. All calibrations are traced back to the UK Primary standards and then to the international prototype of the kilogram. The Centre maintains three weight sets (two E2 and one F1) which are calibrated by the National Weights and Measures Laboratory and a one tonne stainless steel weight calibrated by the National Physical Laboratory.
From 1 milligram stainless steel weights almost too small to see to one tonne cast iron block weights, the Calibration test Centre can calibrate weights to your requirement.
