What is the instrument used to measure heavy masses?

Answer 1

How heavy is heavy. Would you call a car heavy? would you call a bag of Potatoes heavy? They both are I suppose . Vehicles of all weights are weighed on a public Weigh-bridge. They can weigh very heavy loads up to about 100 Tonne, and are usually owned by local Councils. Objects more than about 10 Kilogram are usually weighed on a portable Weighing Platform. Example: Airports, Scrap Metal Buyers, Farmers, etc. use Weighing Platforms which are about 1Metre square, for weights in the approximate range of 5 to 500 Kilogram. Bathroom Scales can cope with up to about 150 Kg and are useful for weighing objects other than humans. Example: domestic luggage.
