Understanding Olive Oil Conversions
The Math Behind This Conversion
To convert 1 ounces of olive oil to grams, multiply by 28.3495 (the number of grams per ounce). So 1oz × 28.3495 = 28.3g.
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.
