For 100 g butter, these planning ratios give 75 g liquid oil, 80 g coconut oil by the mass rule, or 75 mL by the volume rule.

Liquid oil mass = 0.75 × butter mass; coconut oil mass = 0.8 × butter mass; coconut oil volume in mL = 0.75 × butter mass in g.

Enter these known values and leave the other values blank.

These are empirical substitution ratios, not physical mass conservation. A successful substitution depends on the recipe and butter water content.
The volume rule and mass rule imply coconut oil density 80/75 g/mL. This is a planning convention, not a measured coconut oil density.
Gram-based ratios apply to butter or a butter-like spread only when the recipe can tolerate the replacement. Margarine composition varies.
The captured kitchen-unit conversions use ingredient-specific fixed weights. Use mass measurements for reproducibility and do not treat cup measures as exact ingredient densities.

Oil changes water, fat structure and aeration. The ratios estimate amounts but do not promise identical texture.

They are separate planning rules. Their implied density is a convention rather than a laboratory measurement.

Declare the physical or stated approximation domain; captured arithmetic is unchanged.
