Customary System Conversion Chart Today, some of the systems of units in use include the metric system, the imperial system, and the united states customary units. the international system of units (si) is the standard metric system that is currently used, and consists of seven si base units of length, mass, time, temperature, electric current, luminous intensity, and amount of.

Metric And Customary Unit Conversion Charts Length. for measuring length, the u.s. customary system uses the inch, foot, yard, and mile, which are the only four customary length measurements in everyday use. from 1893, the foot was legally defined as exactly 1200⁄3937 m (approximately 0.304 8006 m). [13] since july 1, 1959, the units of length have been defined on the basis of 1 yd = 0. Measuring length. 12 inches = 1 foot. 36 inches = 1 yard. 3 feet = 1 yard 5280 feet = 1 mile 1760 yards = 1 mile. Us customary units of length include inches (in), feet (ft), yards (yd), and miles (mi). 1 ft = 12 in. 1 yd = 3 ft = 36 in. 1 mi = 1760 yd = 5280 ft. the various units of length are used for different purposes: inch: used to measure small lengths such as a phone screen size. feet: used to measure small medium lengths such as the height of a ladder. Use the us customary to metric units’ equivalence: 0.62 mile (mi) = 1 kilometer (km), 1 km is equal to 1000 meters (m), and 1 hour = 60 minutes. solution. convert 40 miles in two hours to kilometers per hour. 40 mi 2 hrs ⋅ 1 km 0.62 mi = 32.2581 km hr 40 mi 2 hrs ⋅ 1 km 0.62 mi = 32.2581 km hr. convert 32.2581 kilometers per hour to.

Unit conversion is a multi step process that involves multiplication or division by a numerical factor, selection of the correct number of significant digits, and rounding. this multi step process is presented in nist sp 1038 2006 (section 4.4), including a rounding procedure for technical documents, specifications, and other applications.
