If we travel to the United Kingdom or the USA we should be careful with the road signs. They use a different system of measurement called The Imperial System.
1 mile /maɪl/ = 1.609344
kilometres /kɪˈlɒmɪtə/
When they talk about how tall they are, they also use different units as the ones we use.
1 foot /fʊt/ ( pl feet
/fiːt/) = 0.3048 metres /ˈmiːtə/
1 inch /ɪntʃ/ = 2.54
centimetres /ˈsɛntɪˌmiːtə/
