Other countries have adopted the system but do not use it in all cases, for example road distances and speeds are still measured in miles and miles per hour in the United Kingdom.

Most countries in the world use the metric system, and consequentially use the gram. The EU uses the gram, as well as Canada, Australia, and New Zealand. There are many countries that use the gram, and thus, it would be very difficult to name them all.
