Normalize volume
120 cm3 stays 120 cm3.
Precision mineral weight calculator
Estimate the weight of solid quartz specimens by volume, then tune the density for purity, inclusions, and cut quality.
Visual conversion flow
The crystal cluster expands with volume, the central lens responds to density, and the balance scale settles at the calculated pound weight.
Formula
120 cm3 stays 120 cm3.
120 cm3 x 2.65 g/cm3 = 318.00 g.
318.00 g / 453.59237 = 0.70 lb.
