Metric and English Symbols


You can measure most items in either English units or metric units. To do so, you must (1) know the type of unit used in the measurement, and (2) have an instrument that can measure a specific object in those units. To measure length in inches, for example, you would use a ruler marked in inches. To check weight in kilograms, you would use a scale calibrated to measure the number of kilograms.

Next, we'll learn the symbols for the units used to measure mass, volume, length, and temperature, and which devices are used to measure them.
