The actual length of an inch has varied becuase of variances of the length of a foot. Throughout history it has been equal to 1/12 - 1/16 of a foot, but there are now exactly 12 inches in a foot. In 1959 the world agreed to the exact length of the national yard, .9144 meters. As such a foot is equal to .3048 meters and an inch is equal to 2.54 centimeters.
The standard ruler has 12", and metric combinations have 30cm. Inches are also often measured using tape measures which commonly come in lengths from 6' - 35'. Other types of measuring devices include scales, calipers, measuring wheels, micrometers, yardsticks, and even lasers.
We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs. If you need a ruler you can also download and print our free printable rulers which include both imperial and metric measurements.
