International metric standards

In 1875, the International Bureau of Weights and Measures was established in Sèvres, France, by the International Metric Convention, (also known as the Treaty of the Meter), initially signed by representatives of 17 nations. Contributions from signatory goverments support the Bureau, which became the depository for the International Prototypes of the Meter and the Kilogram, and secondary standards. In French, it is known as the Bureau International des Poids et Mesures (BIPM). In subsequent years, additional nations joined, so by 2012 there are 53 member states, including all the major industrialized countries. The Convention thus provides the organizational structure for international agreements concerning matter relating to units of measurement. Each 20 May is now World Metrology Day.«[Original logo of the BIPM.]

Jigsaw puzzle

A group of girls walks into a bar. One of the women tells the bartender to line up a row of drinks for all of them. The gals lift their glasses and toast: "Here's to 51 days!" and they proceed to down their drinks.

Once again, they tell the bartender to "line 'em up" and once again they toast 51 days and down their drinks.

The bartender says: "I don’t get it. Why in the world are you toasting 51 days?"

One of the girl explains: "We just finished a jigsaw puzzle. It had written on the box '2-4 years' but we finished it in only 51 days!"
