What is the definition of meter?

Answer 1

The meter (m), is the base unit of length in the International System of Units (SI). Originally intended to be one ten-millionth of the distance from the Earth's equator to the North Pole. Since 1983, it is defined as the length of the path travelled by light in vacuum in 1⁄299,792,458 of a second

Answer 2

The word meter, from the Greek metron, "a measure," has three basic meanings: 1 the measured rhythm characteristic of verse; 2 a unit of length equal to 1,650,763.73 times the wave-length in a vacuum of the orange-red radiation of krypton 86; 3 a device to measure time, distance, speed or intensity, or to indicate volume or flow.

Meaning 2, the meter as a unit of length ( roughly 39 inches), partly explains why only a machine could love the Metric System.

=====================================

Answer #2:

Definition #2 above is no longer the SI definition of the meter length. It's now defined as

1/299,792,458 of the distance that light travels in one second in vacuum.

Definition #3 above could also include voltage, current, resistance, inductance, capacitance,

light intensity, sound pressure level, air pressure, watt-hour, frequency, power, etc.

The cryptic and sardonic comment at the end of Answer #1 above reminds us that the only

places where the metric system knocks people for a loop are Liberia, Myanmar, and the USA.

noun

the fundamental unit of length in the metric system, equivalent to 39.37 U.S. inches, originally intended to be, and being very nearly, equal to one ten-millionth of the distance from the equator to the pole measured on a meridian: defined from 1889 to 1960 as the distance between two lines on a platinum-iridium bar (the "International Prototype Meter") preserved at the International Bureau of Weights and Measures near Paris; from 1960 to 1983 defined as 1,650,763.73 wavelengths of the orange-red radiation of krypton 86 under specified conditions; and now defined as 1 / 299,792,458 of the distance light travels in a vacuum in one second. Abbreviation: m

noun

1.

Music .

a.

the rhythmic element as measured by division into parts of equal time value.

b.

the unit of measurement, in terms of number of beats, adopted for a given piece of music. Compare measure ( def. 14 ) .

2.

Prosody .

a.

poetic measure; arrangement of words in regularly measured, patterned, or rhythmic lines or verses.

b.
