Malt Colour Units for a grist.
MCU = Σ (weight_lb × colour_°L) / volume_gal Copy
MCU = Σ (weight_lb × colour_°L) / volume_gal
The definition is in US customary units because every published SRM fit was regressed against it, so we convert the kg/L inputs here and nowhere else.
Colour is set in the kettle, so the volume passed in is normally the post-boil volume (CalculationOptions.colorVolumeBasis).
