Measurement
Pronunciation: /ˈmɛʒ ər mənt/ ?
Measurement is assigning a number to a
location
based upon a
unit
measure^{[1]}. For example, if one is using the metric system of distance, the unit measure is
1 meter. A measure of 2 meters is twice as long as a measure of 1 meter. A measure of
0.5 meters is half as long as a measure of 1 meter.
Common measurements include distance, time, mass, energy, force and angle.
A metric space is a geometric
space
with a method of measurement assigned to the space.
Measurement error is an important consideration. When measuring
with any device, one is approximating the measure. For example, if the length of a piece of
paper is measured with a metric ruler, typically the measurement is accurate to only
1 millimeter. Since the measurement is not mathematically exact, it introduces an error.
