Understanding Olive Oil Conversions
The Math Behind This Conversion
To convert 1 us teaspoon of olive oil to gram, we use the density of olive oil (0.91 g/ml). A us teaspoon contains 4.93ml, so 1 us teaspoon equals 4.93ml. Multiplying by the density: 4.93ml × 0.91 g/ml = 4.5g.
US vs Metric Cups: Why It Matters
When converting olive oil, the cup size matters significantly. A US cup (236.6ml) of olive oil weighs 215g, while a metric cup (250ml) weighs 228g—a difference of 12g (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 olive oil 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.
