When preparing a big holiday meal, it's not uncommon to have to double or even triple a recipe. That's called scaling a recipe, and it's usually pretty straightforward.

Occasionally, though, you might find yourself dealing with some unusual or otherwise cumbersome units of measurement. For example, if a recipe calls for 2 teaspoons of baking powder and you triple it, now you need six teaspoons. You could measure out six teaspoons, but that's a bit tedious. Is there an easier way? Just consult this handy conversion tool and you'll see that six teaspoons is equivalent to two tablespoons.

I find the tool to be endlessly fascinating. Maybe it's just me, but it's somehow mesmerizing to know that a gallon is equal to 768 teaspoons. Which may not have much practical application — unless one day I find myself stranded on a desert island with nothing but a gallon container and a teaspoon. And a laptop with an internet connection. And I'm baking a very large cake.
