You might abbreviate the word measurement to measure., meas., or M., on a recipe card, on a lab report, or on shorthand notes. It is also common to see such abbreviations in headlines or newspaper titles where space is of concern. Outside of these specific instances, the word is not abbreviated in general prose.
The metric system is an internationally agreed decimal system of measurement created in France in 1799. The International System of Units (SI), the official system of measurement in almost every country in the world, is based upon the metric system. In the metric system, each basic type of measurement (length, weight, capacity) has one basic unit of measure (meter, gram, liter). Conversions are quickly made by multiplying or dividing by factors of 10. It is as simple as moving the decimal point to the right (for smaller prefixes) or to the left (for larger prefixes).
