Peanut Butter
US Cup to Metric Cup
Understanding Peanut Butter Conversions
The Math Behind This Conversion
Converting 1 us cup to metric cup is a direct volume conversion. One us cup equals 236.59ml, and one metric cup equals 250ml. So 1 us cup (236.59ml) equals 0.9 metric cup.
Measurement Tip
Measuring peanut butter by volume is notoriously inconsistent because the pieces don't pack uniformly. Weighing with a kitchen scale gives much more reliable results. The density value we use (1.08 g/ml) represents an average, but your actual measurement may vary by 15-20%.
About Our Data
The density value of 1.08 g/ml for peanut butter is from the USDA FoodData Central database (ID: 172470). This measurement was taken with peanut butter firmly packed into the measuring cup.
