How we calculate these values

Every value on this page for #ac4b21 is computed, not guessed. We convert from sRGB to each space with the standard formulas, so the codes match what design tools show. The uncoated cmyk build carries more ink than the coated one, which is what a printer would compensate for when the same color runs on a rougher stock. The Pantone figure is the nearest match in our reference set by perceptual distance and it is an approximation, not an exact spot color.
