Key Facts about Olive / Cooking Oil
Lighter Than Water
Oils have a specific gravity of ~0.91 to 0.92, meaning they float on water and weigh roughly 8.5% less per teaspoon than water (4,929 mg).
Calories & Healthy Fats
1 teaspoon (~4,500 mg) of pure olive oil contains 40 calories and 4.5 grams of fat, rich in monounsaturated oleic acid.
Solid vs Liquid Coconut Oil
Virgin coconut oil solidifies below 76°F (24°C). When scooped solid, 1 tsp can pack slightly denser (~4,600 mg).
How to Convert a Teaspoon of Olive / Cooking Oil to Milligrams
Teaspoons measure volume. Milligrams measure mass. To convert between them you need the substance density.
For Olive / Cooking Oil, the density is approximately 0.916 g/mL. Culinary oils average ~0.916 g/mL (range 0.914–0.924). 1 US tsp = ~4,515 mg.
Formula
mg = tsp × 4.92892 mL × 0.916 g/mL × 1000Example: 1 tsp of Olive / Cooking Oil = 1 × 4.92892 × 0.916 × 1000 = 4,514.89 mg
Methodology and density source
Density is a representative reference value. Product labels or manufacturer specifications should take priority when available.
The calculation uses the stated 0.916 g/mL density and the selected teaspoon standard. It does not infer a nutritional serving size or a medical dose.
For measurement definitions, see the teaspoon-to-milligram methodology.
Accuracy limitations
This is an estimate: spoon level, packing, particle size, moisture, temperature, and density can change the result.
Use a calibrated scale when the result matters. Level the spoon and identify whether the ingredient is loose, sifted, or packed.
