More rhymes

I talked about rhymes in my last post. Here, I'd like to talk about a few more. Here's one:

A liter of water's a pint and three quarters

And here's another:

Celsius to Fahrenheit

Times by two, add twenty-eight

These ones, and the one about jam in my last post, were popular when I was a primary school student. They were designed to help us move from the Imperial system of measurements to the metric system.
