Most trash cans don’t hold exactly the labeled volume. They’re like “one-size-fits-all” hats—optimistic lies. A 13-gallon can from IKEA might actually hold 12.7 gallons because the shape tapers at the bottom. That’s 48.1 liters. Suddenly, you’re a mathematician arguing with a plastic bucket.
And don’t even get me started on “tall kitchen” cans. Those monsters are 13 gallons but shaped like a wizard’s hat. They hold less actual trash because air gets trapped. In liters? Still 49, but with more regret.
