Why you need to measure (exactly)

Running out of resin mid-pour is one of the most stressful experiences you can have as a maker. You're standing there with a half-filled river table and the clock is ticking while the resin starts to set. I've been there, and it sucks. This calculator is here to make sure that doesn't happen to you.

The math is basic geometry, but the weight conversion is where people usually trip up. Most resins aren't light like water; they're denser. 1.1g/ml is a safe average, but check your bottle. And a pro tip: always mix about 5-10% more than you think you need. Between what sticks to the bucket and what drips off the edges, you'll be glad you had that extra cup.
