Measuring 16 oz (1 lb) of Pure Maple Syrup in the Kitchen

Because 1 US Customary Cup (236.6 mL) of pure maple syrup weighs 312g when measured poured liquid, 16 Ounces (453.6g) translates to 1.45 US cups (1 ⅓ cups + 1 tbsp + 2 ¾ tsp). By contrast, using the boiled down / maple cream measure (325g/cup — a 13g per-cup shift), 16 oz occupies 1 ⅓ cups + 1 tbsp (1.40 cups).

Without a kitchen scale, measure 1 ⅓ cups + 1 tbsp + 2 ¾ tsp (23.26 tablespoons total) using poured liquid technique. Pour at eye level in a liquid measuring cup on a flat surface, or weigh in a bowl on a digital kitchen scale.
