The English system is no longer used in New Zealand. However; despite the fact that metrication occurred here back in 1969, remnants of the Imperial system it can still be found in everyday use.
-meter sticks are called yardsticks
-people will refer thousands of pounds instead of metric tons
–tablespoons, teaspoons, etc. are units of measurement in baking
-people will talk about miles per gallon, not kilometers per liter
-at the bar, people order pints of beer, even though what they’re getting is usually 375mL
This duality of measurement seems counterintuitive to me, but the natives seem to get along just fine. If there are any locals reading this, perhaps you wouldn’t mind weighing in on how you manage officially in metric and colloquially in Imperial?
