The saying “two nations divided by a common language” is attributed to George Bernard Shaw, and popularised by Winston Churchill, refers to the United States and the United Kingdom that while they share the English language, there are significant differences in spellings and meanings. This is also true of many words and terminologies we use in woodworking. While many of them are just spelling differences some of them mean entirely different things.

The Imperial or English measuring system used in the USA originated in Britain and consists of inches, feet and yards: 12 inches to a foot and 3 feet to a yard. The UK has adopted the Metric system that most of the world uses and it consists of millimetres, centimetres and metres: 10 millimetres to a centimeter and 100 centimetres to a metre. To convert: 1 inch equals 25.4 millimetres. Fortunately, it is possible to get tape measures with both measuring systems.
