Measuring 16 oz (1 lb) of Water in the Kitchen

Because 1 US Customary Cup (236.6 mL) of water weighs 237g when measured poured liquid, 16 Ounces (453.6g) translates to 1.91 US cups (1 ¾ cups + 2 tbsp + 1 ¾ tsp).

Without a kitchen scale, measure 1 ¾ cups + 2 tbsp + 1 ¾ tsp (30.62 tablespoons total) using poured liquid technique. Place a liquid measuring cup on a flat countertop and read the water meniscus at eye level. Standard water has a pure density of 1.00 g/mL, making 1 US cup exactly 237 grams (or 236.6g).

Source note: NIST Standard Reference Data; 1 US customary cup = 236.588 mL = 236.6 g pure water at 20°C
