Oh, yes. 100 meters are 100 meters all over the world, even at high school and the olympic games.
I could be wrong, but I think 1896, the fastest time was 13.0 seconds.
The Olympic Games have always used the metric system (i.e. from the first modern Olympic Games in 1896).
There has never been a 100 yards race in the Olympic Games.
100 meter dash
The 100 yard dash was included in the Olympic decathlon until 1904, and was part of the Commonwealth Games until 1966.
Running 100 meters means you have run 109.361 yards.
they don't do yards in the Olympics
50 yards = 45.7 metres.
