Required ice mass calculator

Ice mass is based on latent melting capacity; include the usable fraction rather than gross ice capacity.

Units

m = \frac{12{,}000 \times C \times 100}{144 \times u}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

m = \frac{12{,}000 \times 350 \times 100}{144 \times 85} \approx 34{,}314

Symbol	Meaning	Unit

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
