100 meters is equal to 109.36 yards. In formulaic terms, 1 meter is equal to 10,000/9,144 yards, and 100 meters is equal to 100*(10,000/9,144) yards. Both numerical calculations extend to many decimal places.
A meter is the basic unit of length in the metric system, also known as the International System of Units. The majority of countries around the world have adopted the International System of Units, but a few countries — including the United States, the United Kingdom and a few countries from the former British Empire — still use the yard. In some cases, the UK and other former British countries utilize both forms of measurement.
