An inch is a unit of length commonly used in the imperial and US customary systems of measurement. It is symbolized by “in” or a double prime symbol (“). One inch is equal to 25.4 millimeters. It is primarily used for smaller measurements, such as the height or width of objects.
A millimeter is a unit of length in the metric system. It is represented by the symbol “mm” and is equal to one-thousandth of a meter. Millimeters are frequently employed for precise measurements, particularly in fields such as engineering, manufacturing, and scientific research. They offer a finer level of detail for measuring small objects or dimensions.
1″ = 25.4mm
Distance d in millimeters (mm) is equal to the distance d in inches (″) times 25.4 i.e.,
d(mm) = d(inch) × 25.4
Example- Convert 1.5 inches to mm
Ans. d(mm) = 1.5″ × 25.4 = 38.1mm
To change inches to centimeters and then to millimeters, use these conversion rules:
1 inch equals 2.54 centimeters
1 centimeter equals 10 millimeters
