Understanding Molasses Conversions
The Math Behind This Conversion
To convert 1 us teaspoon of molasses to gram, we use the density of molasses (1.41 g/ml). A us teaspoon contains 4.93ml, so 1 us teaspoon equals 4.93ml. Multiplying by the density: 4.93ml × 1.41 g/ml = 7g.
US vs Metric Cups: Why It Matters
When converting molasses, the cup size matters significantly. A US cup (236.6ml) of molasses weighs 334g, while a metric cup (250ml) weighs 353g—a difference of 19g (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
Measure molasses in a liquid measuring cup (the kind with a spout) placed on a flat surface. Read the measurement at eye level, looking at the bottom of the meniscus (the curved surface of the liquid). For sticky liquids like honey, lightly coat the measuring cup with oil first to help it slide out easily.
