Need to convert fractions of an inch into millimeters, or vice versa? That’s where inches charts come in handy. These handy tables visually display inch measurements in fractions, decimals, and millimeters, making conversions quick and easy.
Fractional to Decimal Conversion
Inches are often represented as fractions, such as 1/2, 1/4, or 1/8 of an inch. Understanding these fractions is essential for precise measurements in all kinds of fields, from construction to crafting.
The easiest way to convert a fractional inch into a decimal is to divide the top number (numerator) by the bottom number (denominator). For example, to convert 1/4 inch to a decimal, you’d divide 1 by 4, which equals 0.25 inches.
Decimal Inches and Millimeter Equivalents
Inches can be expressed as decimal numbers, such as 0.5, 0.25, and 0.125. You’re probably already familiar with some of the more common decimal inch values, such as 0.5″ equaling 1/2″, 0.25″ equaling 1/4″, and 0.125″ equaling 1/8″.
Millimeters are commonly used in the metric system, so it can be helpful to convert inches to millimeters. To do so, you can multiply the number of inches by 25.4 to get the equivalent measurement in millimeters. For example, 1 inch equals 25.4 millimeters.
