Says a person from a country that still refuses to adapt the metric system. :P

Saying 5 feets is actually faster then saying 150 centimeters or 1 meter and 50 centimeters :P. In Canada we use both system depending on the situation, officially its the metric system but for things like my example we use the imperial system.

Saying 1 metre is faster than saying 3.28 feet. You can't just pick a round number for the imperial system and thus say that it is better than the metric system, where it isn't a round number
