Calculate batch quantities and container counts for weekly meal prep.
Container count depends on whole portions fitting rather than on total volume, so a container holding 1.8 portions effectively holds one. Rounding down before dividing avoids under-ordering. Food safety limits refrigerated prepped meals to about four days, so prepping beyond that requires freezing rather than simply more containers.
