A simple little animation: Interactive Thermometer

Opinions?

Why do some people still use Fahrenheit in this day and age? What good is it anyway?

Yeah, and why do people still use the Imperial System instead of Metric!

Fahrenheit tends to only be used when measuring warm temperatures.
When you're on holiday, you say "Ooh, it's over 90 degrees!", but then when you get back and it's horrible and cold, you switch and complain that it's only 5.

Of course, that only applies to casual use, Celsius (or even Kelvin) is always used in scientific situations.

What I don't get is how Fahrenheit got defined.
Celsius is easy enough: 0 is freezing, and 100 is boiling.
Kelvin is fairly simple too, that's just Celsius but shifted so that absolute zero is now 0.

But Fahrenheit is trickier. Freezing is 32, boiling is 212, and there doesn't seem to be any logic in how the scale was made up. Maybe there is and I'm just not seeing it.

It's nice. Nice pictures.
I wish my mouse had more pixels though,
so I could narrow in on a measurement.
And this is a "formula"!, a subset of an equation.

The human body is ~100 Fahrenheit

I like the interactiveness of the thermometer, and it serves as a good reference for conversions.

but still the converter is better.
