How many Inches in a Foot?
There are exactly 12 inches in a foot, according to the modern definition of both units. Historically, in some locations and at different time periods an inch was defined as 1/16 of a foot, but currently the 1/12 definition is the only valid one. The symbol for inches is "in" while for foot is "ft". Sometimes double quotes and single quotes are used, respectively, for example if a person is 5 feet 3 inches tall, that could be written as 5'3".
Difference between Feet and Inches
Feet and inches are both units of length, but of different magnitude. Inches are more appropriate for measurements of the dimensions of smaller objects and very small distances. For example, while the length of a pole might be measured in feet, its diameter will often be given in inches, e.g. 10 feet high and 5 inches in diameter.
The foot is most likely the older unit of the two and it existed in many different locations and time periods. In medieval Europe it was defined by measuring the length of the feet of a number of men, randomly selected from a local community, and then taking the arithmetic average. It thus had varying length - usually between 250mm and 335mm. An inch was sometimes defined as 1/12 of a foot, and in others - as 1/16 of a foot. The first written definition that reached us is from 1324 England and it defines in terms of "three grains of barley, dry and round, placed end to end, lengthwise".
