In 1791 the French Academy of Science defined the metre as one ten millionths of the distance from the North Pole to the equator along the meridian through Paris.

In 1875 the Metre Convention agreed to set up a permanent International Bureau of Weights and Measures (BIPM, after its French acronym) in SÃ¨vres, France. Here, the international metre was the distance between two lines on a standard bar composed of an alloy of 90% platinum and 10% iridium, measured at the melting point of ice. Copies of the prototype were sent to national standards organisations in other nations.

Although it was later discovered that because of the shape of the earth this measure was not quite one ten millionths of the pole-to-equator distance, the definition remained.

In 1960, a metre was more finely defined as 1 650 763.73 wavelengths of the orange-red emission line in the electromagnetic spectrum of the krypton-86 atom in a vacuum.

In 1983 the metre was redefined in terms of the second and the speed of light. It is the path travelled by light in vacuum during a time interval of 1/299792458 of a second.

The organisation responsible for this definition (and previous versions) is the General Conference on Weights and Measures (CGPM: ConfÃ©rence GÃ©nÃ©rale des Poids et Mesures).

If you can trust the person who told you it's a 400 meter track, then no calculation is necessary. The length is 400 meters.

It depends on the track length.

The straight would be 50m.

The 50 meter dash is an eighth of the track, or half of the straightaway. So basically half the length of a fottball feild.

The number of laps is50/(length of one lap on the track you choose)

The difference depends on the length of the turns as well as the width of the lanes. A track with 42 inch lanes will be different than a track with 36 in lanes. Also a track with 110 meter turns and 90 meter straights will be different than one with 100 meter turns and straights.

55 meter dash for indoor track and 100 meter dash for outside track

College tracks, along with high school tracks, are 400 meters in circumference. This is the normal, professional size track length. Olympians have this track as well. There are indoor, shorter 200 meter tracks, but generally there will be a 400 meter outdoor track. that means 4 laps to a mile. College, however, runs different distances. most notably, the 1500 meter instead of the 1600. 100 meters short of a mile, however it makes more sense metrically. (1.5 km)

Yes it does measure LENGTH in the metric system.A meter measures length.

meter is the standard unit of length

TRACKS ARE 400M IN LENGTH! Hope that helps!

Depends on the track. If it is a standard 400 meter track, it will be eight laps. If it is indoors it will be about thirteen.

The exchange zone on a 400 meter track is 20 meters long. For races involving 200 meter legs or less, a 10 meter acceleration zone may be marked on the track and used by the runner receiving the baton to accelerate to match speed with the incoming runner. With or without an acceleration zone, the baton must still be exchanged within the official 20 meter zone.

people test the rollercoaster to see if there are any minor problems and when they finish it, they let people ride on it. the track keeps it on track

The bank and its database keeps track of all deposits and withdrawals done on all its accounts.

Four laps of a 600 meter track equals about 1.5 miles.

A meter of what? Meter is a unit of length, not of weight.
