What is the standard unit for length?

Answer 1

metre

Answer 2

The basic unit is the metre or meter. However, there are several other units within the metric system that are fractions of the meter and are sometimes more appropriate when defining the length of certain objects. These are the millimeter (mm) which is one-one thousandth of a meter (1,000 mm in a meter), the centimeter (cm) which is one-one hundredth of a meter (10 mm in a cm, 100 cm in a meter), the decimeter (dm) which is one tenth of a meter (100 mm in a dm, 10 cm in a dm, 10 dm in a meter), and the kilometer which is one thousand meters (1,000 meters in a kilometer). There are different terms because it is more useful to know km when measuring the length of china and mm when measuring the length of a lady-bug and so on.

Answer 3

One of the kings of England - they measured the length of his foot and

that became the legal standard of measure. In 1793, France adopted the metre as its official unit of length. It represented 1/ 40,000,000 of the circumference of the Earth through the poles. The precise length of a meter has been adjusted a few times since then and is now determined by the distance light will travel in a fixed amount of time. The standard unit of length is meter. Meter is the SI unit. But in some units that are considered for length are foot and yard.

Answer 4

By unit of length and distance and conversion ,we can say that Metric unit for measuring length is meter.

+++

The metre (to use its correct French spelling) is the SI standard unit of length, and for practical purposes we use its milli-, micro- and nano- divisions downwards, and its kilo- multiplier upwards.

'

The centimetre is in common day-to-day use for clothes sizes and the like, but is not a "preferred unit" and is not used in science and engineering, save for the cubic centimetre (cc) in chemistry and engine specifications.

'

Agriculture and forestry use the Hectare (Ha) for area but otherwise areas are in square metres, or the square mill-, micro-, nano- metre down; and square kilometre upwards.

'

Whilst numerically all right, the "Mega" multiple is rare or non-preferred here. In fact I have only ever seen Mega tacked onto Newtons (force or weight), Pascals (pressure), litres (liquid volume) and electrical units.

'

The deci- and deca- factors in any measurements, are rarely, if ever, used.

'

Avoid mixing multiples / divisors - don't say "3m 55mm", but instead say "3055mm" or (better) "3.055m" ("Three-point-nought-five-five").

centi(-meter,-liter,-gram)

(smallest) milli(-meter,-liter,-gram)

Answer 6

In 1793, France adopted as its official unit of length a metre, based on provisional results from the expedition as its official unit of length. Although it was later determined that the first prototype metre bar was short by a fifth of a millimetre due to miscalculation of the flattening of the Earth, this length became the standard. The circumference of the Earth through the poles is therefore slightly more than forty million metres.

Answer 7

It is meter
