Understanding Sour Cream Conversions
The Math Behind This Conversion
To convert 1 us teaspoon of sour cream to gram, we use the density of sour cream (0.97 g/ml). A us teaspoon contains 4.93ml, so 1 us teaspoon equals 4.93ml. Multiplying by the density: 4.93ml × 0.97 g/ml = 4.8g.
US vs Metric Cups: Why It Matters
When converting sour cream, the cup size matters significantly. A US cup (236.6ml) of sour cream weighs 229g, while a metric cup (250ml) weighs 243g—a difference of 13g (6%). If you're following a recipe from a different country, using the wrong cup size could affect your results. American recipes use US cups, while recipes from Australia, UK, and most other countries use metric cups.
Measurement Tip
For room-temperature recipes, let sour cream sit out for 15-20 minutes before measuring. Cold sour cream is slightly denser than room-temperature sour cream, which can affect very precise recipes. Our density of 0.97 g/ml is based on refrigerated sour cream.
