About Cups
A cup = 8 fl oz = 16 tbsp ≈ 236.6 mL - the fundamental unit of American cooking. Almost every US recipe uses cups for dry and liquid ingredients. The US customary cup (236.588 mL) differs from the US legal cup (240 mL, used in nutrition labelling) and the metric cup (Australia/Canada: 250 mL). Kitchen sets come in 1/4, 1/3, 1/2, and 1 cup sizes. 2 cups = 1 US pint.
About Pecks
A peck (pk) is a dry volume unit in the US customary system equal to 2 dry gallons or 8 dry quarts - approximately 8.810 liters. It was historically used to measure grain, produce, and bulk goods at market - a 'peck of potatoes' or 'peck of apples' was a standard quantity. The nursery rhyme 'Peter Piper picked a peck of pickled peppers' has made the peck culturally familiar even though it is rarely used in modern commerce. Four pecks equal one US bushel. In agriculture, pecks still appear in older US crop yield tables, traditional market records, and historical American cookbooks.
