How Many Millimeters Are In 1 Inch? 1 inch is equal to 25.4 millimeters (mm). By definition, an inch is equal to 2.54 centimeters (cm). A millimeter is the tenth part of a centimeter. Therefore, to get a value of one millimeter, a centimeter has to be divided by ten. Converting from millimeters to inches would equal 2.54 divided by 10. The value returns 25.4 mm.
A look at history would provide a better understanding of the inch definition. The metrics of inches date as far back as the 1100s when king David I defined the imperial unit of an inch as the breadth of a man’s thumb. These metrics stayed for over three hundred years until king Edward II adjusted the customary units. The value of an inch introduced by King Edward was the length of three dried round grains of barley placed side by side.
it was in 1959 that the international community finally set the value of an inch under the standard unit of measurement or systems of measurement at 2.5 centimeters (cm). This metric is what we’ve used to this day. Knowing the standard value makes it easy for anyone to convert from inch to any other system of measurement. However, there are different equivalents of inches in other metric systems. For example, the value of an inch in yards is 1/36 or 0.028 yards.
This article answers questions bothering around the conversion of millimeters into inches and explains how to apply simple arithmetic to take a measurement from inches to millimeters.
