Explanation

A combination or group of letters that represent larger words are known as abbreviations. Abbreviations are sometimes used to represent units of measurement. Abbreviations may or may not be followed by a period. When abbreviations contain capital letters, the literary rules for capitalization should be followed. Remember that the effect of the double capitalization indicator ends when a space or non-letter occurs.

A space should be left before and after an abbreviation and a numeral or letter, a sign of operation, a sign of comparison, a monetary sign, a percent sign, a sign of omission, or any other mathematical symbol.

If an abbreviation is only a single letter or would be misread as a short-form word, an English letter indicator must be used before the abbreviation unless the abbreviation is followed by a period.

Contractions for the words to, into, and by should not be used before an abbreviation.

Some common abbreviations for measurement of time, temperature, length, and weight are as follows:
