I wish we used the metric system
But we don’t, so ya gotta learn the other one
It’s easy with the metric system
But the other one’s the one we use
An ounce weighs the birthday card you got in the mail
One pound weighs sixteen ounces when it's put on a scale
A stone is fourteen pounds, a pennyweight less than one
And in the U.S.A. two thousand pounds are a ton
These numbers all fill up my head
And that is why I've always said
I wish we used the metric system
But we don’t, so ya gotta learn the other one
It’s easy with the metric system
But the other one’s the one we use
You can use the inch to measure just how long is a worm
If you have 12 inches then it’s called a foot, that’s the term
One yard is three feet, and it could take a while
To walk a thousand-seven-hundred-sixty, that's a mile
A league is three miles and you might be
Twenty thousand of them under the sea
I wish we used the metric system
But the other one’s the one we use
When you’re making cookies you might need a teaspoon of salt
A tablespoon’s three teaspoons, and it’s not your fault
If dont know that two tablespoons are called a fluid ounce
Because eight fluid ounces make a cup and that’s what counts
Two cups are a pint and two pints are a quart
Four quarts are a gallon or five fifths, if you’re that sort
We wish we used the metric system
But the other one’s the one we use
The other one’s the one we use
The other one’s the one we use
