A system of measurements used widely in most advanced countries, with the exception of the United States. The metric system uses as its basic unit of length the meter (equal to 3.3 feet, or 39.6 inches), as its basic unit of volume the liter (equal to 1.06 quarts), as its basic unit of mass (weight) the gram (equal to 0.035 ounces), and as its basic unit of temperature the Celsius degree. Most software programs allow measurements to be made in either English or metric units. Most high-end scanners and other devices utilize metric measurements, as well. (See also Metric-to-Inches Conversion and Inches-to-Metric Conversion.) Multiple qualities of bytes are also measured using metric prefixes. See Metric Prefix.
