I when tried to construct a custom-sized aquarium for a completely specific breed of bioluminescent shrimp I bought from a guy in a dark alley. Okay, most likely it wasn't a dark alley, but it was unconditionally a unreliable Craigslist ad. I had the glass. I had the silicone. I had a ruler that was missing the first three millimeters. What I didnt have was a clue. I kept staring at the glass panels, wondering, "Wait, how to determine litres from centimeters?" It felt past I was aggravating to solve a riddle posed by some ancient math-obsessed sphinx.

Calculations are annoying. They just are. We live in a world where we desire the volume of aquarium calculator of our coffee mugs and our garden ponds to just magically appear in our heads. But the universe demands rave review in the form of arithmetic. If you have ever felt physically hard done by by the sight of a measuring tape, you are in the right place. Lets fracture the length of the logic of liquid volume without making your brain leak out of your ears.

Before we get into the "how," lets talk more or less the "why." Why attain we use centimeters at all? Why not inches? Or cubits? Or the length of a medium-sized banana? Centimeters are glorious because they belong to the metric system. The metric system is a neat, clean room where everything fits into boxes of ten. It is the Marie Kondo of measurement systems.
