Celebrate World Measurement Day
Today is World Metrology Day. It marks the anniversary of the signing of the Convention de Metre in 1875, which provided the basis for a single, coherent system of measurements. But why should you care?
Well, without what is known as the International System of Units (SI units), we would have no agreed standard with which to measure the world around us.
It guarantees that a kiliogram weighs a kilogram the world over. It ensures that, if you travel a kilometre away from home, you know exactly how far you have travelled, and that if you arrange to have dinner with the wife at six o clock, you won't find it already in the dog.
