Do people outside of the US use rulers in US Customary and Metric, or just metric?
This may sound a bit silly of me to ask, but it kinda bugs me. Here in the US we use rulers with inches and centimeters on them, and just wondered if they did this overseas, too.
If so, are they in feet (12 in. or about 30.84 cm) or meters/yards?
