How we calculate these values

Here is how the numbers for #2575bb are worked out. 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. For Pantone we return the nearest reference by perceptual distance, which gets you close but is not a substitute for a physical swatch book.
