The American and British inch (and foot) are exactly the same.
The U.S. and Britain signed the Treaty of the Meter (The Metric Act) in 1866 which defined the foot to equal exactly 1200/3937 meters. (This is now called the survey foot)
Then in 1959 the U.S. National Bureau of Standards redefined the foot to equal exactly 30.48 centimeters. Then in 1963 Britain used this definition for the Weights and Measures Act. This is the definition we use today.
