In Europe, you measure height in metres and centimetres.
In the UK and the US, we use the imperial system, and that includes feet and inches. The ‘foot’ was based on 1/3 of the length of King Henry I’s arm. 1 inch is about 2.4 cm. There are 12 inches in 1 foot. I measure 1.74 m, but in the UK people say that I measure 5 feet, 8 and a quarter inches !
Now, the tallest person in the world was Robert Wadlow who lived in the US from February 22, 1918 to July 15, 1940. Unfortunately, he died very young and at his death he measured 8 feet 11 inches, thats 2.72m.
Can you imagine that ? Just look at this film of the gentle giant with his father !
