Metre how long

Within larger regions, units of measure varied widely. More often than not, units of measure at this time were used to determine taxes a piece of cloth, for example, would be taxed based on its length.

Many measurement units were dependent on who was ruling at the time, and they could change on a whim. After the French Revolution began in , and with Enlightenment ideals still popular, a greater emphasis was placed on standardizing units of measurement within the scientific community. At first, there was resistance to the change, but the meter was adopted in America and continental Europe in the mid th century. In at the Metre Convention, the meter became the official international measurement unit.

The goal was to ensure that standard measuring bars were available to every country in the world, but it was impossible to know if the bars were the right length because no one knew for sure whether or not the countries were working with standard and correct measurements.

Something needed to change to make the unit of measurement consistent throughout the world. As science usually does, it set out to improve upon its previous work and find ways to make life easier and put everyone on the same page when it came to the meter. In the s, the French defined the meter as one ten-millionth of the distance from the North Pole to the equator as it passed along a meridian to Paris.

This actual measurement is represented on an iron bar that is housed in Paris. In , the definition of the meter was updated and defined more precisely. For this definition, the meter is the distance from 0 degrees, between the axes of two central lines that are marked on a bar of platinum-iridium. The bar is subjected to standard atmospheric pressure and held on two cylinders, which are at least one centimeter in diameter, and are placed on the same horizontal plane exactly mm from each other.

Examples: Diameter of a swimming pool, length of objects. In order to convert the length given in meters to different units, it is needed to know the relation between the meter and the other units. Hence, while doing the required length conversions, these relations can be used and the lengths can be converted easily from meters to the required units.

Centimeter is also a unit of distance abbreviated as, "cm". Millimeter is abbreviated as "mm". Inches is the USCS unit mainly used to indicate length. It is abbreviated as "in". Feet is also a USCS unit mainly used to indicate length. It is abbreviated as "ft". Foot is the singular unit for feet. Yard is the USCS unit abbreviated as "yd". Let us try converting these units to meters.

We can use our arms with fingers extended and measures to the tips of the fingers. This is a freehand way to estimate meters, although there may be a small difference between actually measuring it with a scale and measuring it with your arm. Learn Practice Download.
