The introduction of decimal currency was just the start. With the Australian ability to count to ten while our hands were full of beer and pies - thank you thongs - the government came over all metric. It took years.
My height changed in fifth grade, when I was ten. We were all lined up against one of those new-fangled metre rulers, to see how tall we were in metric. Inches to centimetres - fantastic. We were suddenly double our height and then some. But feet to metres? Bad enough to become shorter when I was already the shortest in the class (the year, possibly the school), suddenly I was the spokesbody for the new measurement system. How tall was a metre, sir? Jenny, can you just go stand beside that boy? Got it? Or, Sir, how long is two metres? Jenny, just lie here. See, two jennies is equal to two metres. Understand? Yes, sir, I've got it now. If only I'd known about deed poll in 1972. I could have changed my name to Exactly One Metre Tall Heward. Saved a lot of bother. Or One Metre is Equal to 39.37 Inches Heward. I envied babies. They were - still are - measured in imperial as well as metric. Sort of bi-measured. Easily translated. How ever else can one grandmother go boasting to another grandmother about how strapping the new grandchild is?
And how about our weight? We became enormous. I went from three stone to nineteen kilograms. Metrication made us all either really tall and fat, or very short and fat. And as for criminals? For years when the police were on the lookout for a 68 kg 175cm male, I, for one - I know of others - would look for an incredibly big man. I'm surprised criminals didn't make the most of it.
But, in the manner of children, we got more fluent in metric. We became bi-measuring.

There is one problem. It's not the one where we end up with a bit more food, going from imperial to metric. No, there's nothing wrong with having a bit extra. It's those other measurements that are so pesky. A pinch. A smidge. A dash. A glug. All those measurements of taste, a flick of the wrist, a twist of the fingers. If only they'd been more precise.
There must be a conversion chart somewhere...
