The Quick Conversion: 100g to Ounces
To convert grams to avoirdupois ounces, the unit of weight commonly used in the United States, you divide the number of grams by 28.35. Therefore, 100 grams divided by 28.35 gives you the number of ounces. The precise result is 3.5274 ounces, which for most cooking purposes, can be rounded to 3.53 ounces. This universal conversion applies to any food item, including spinach, and is essential for accurate measurement.
Raw vs. Cooked Spinach: The Volume Difference
While the weight of 100g of spinach is constant, its volume is not. Spinach has a very high water content, approximately 91%, which means it shrinks drastically when cooked. This is a crucial detail for anyone cooking or preparing meals, as the amount of raw spinach needed to achieve a certain weight is significantly larger than the amount of cooked spinach for the same weight.
For example, 100 grams of raw spinach takes up a large volume, equivalent to roughly 3 to 3.5 cups, depending on how tightly it is packed. By contrast, 100 grams of cooked spinach is much denser and more compact, typically reducing to only about half a cup. This variation explains why a large bag of fresh spinach can cook down to a surprisingly small portion. Always check whether a recipe specifies raw or cooked measurements to avoid inaccurate results.
Nutritional Changes When Cooking Spinach
Cooking spinach not only affects its volume but also its nutritional profile. While some heat-sensitive nutrients may be lost, cooking can also enhance the absorption of other important minerals.
- Enhanced Mineral Absorption: Raw spinach contains oxalic acid, a compound that can interfere with the body's absorption of minerals like calcium and iron. Cooking the spinach helps break down this acid, making these minerals more bioavailable.
- Vitamin Content: Heat-sensitive vitamins like Vitamin C and folate can be partially lost during cooking, especially with boiling. Lighter cooking methods like steaming or sautéing can help preserve more of these nutrients.
- Antioxidant Levels: The body absorbs certain antioxidants, such as beta-carotene, lutein, and zeaxanthin, more effectively from cooked spinach. Sautéing with a little healthy fat, like olive oil, can further aid the absorption of these fat-soluble vitamins.
Practical Measurement and Cooking Table
For everyday cooking, a food scale is the most accurate tool for measuring 100g of spinach. However, for those without a scale, approximate cup measurements can be used with the understanding that they are less precise.
| Measurement | Raw Spinach | Cooked Spinach |
|---|---|---|
| Weight (Metric) | 100g | 100g |
| Weight (Imperial) | ≈ 3.53 oz | ≈ 3.53 oz |
| Volume (Approximate) | 3 to 3.5 cups | ≈ 0.5 cups |
| Best For Cooking | Salads, smoothies, sandwiches | Stir-fries, sauces, side dishes |
Incorporating Spinach Into Your Diet
Spinach is a versatile vegetable that can be enjoyed in many forms. For maximum nutritional benefits, a balance of both raw and cooked spinach is often recommended. Consider adding raw spinach to your morning smoothie or salad for a boost of Vitamin C, and using lightly sautéed spinach in your evening meals to maximize mineral absorption. When sautéing, using healthy fats like avocado or olive oil can help your body absorb fat-soluble vitamins A and K. Frozen spinach can also be a convenient and nutritious option, with studies suggesting its nutritional values are comparable to fresh spinach. The key is to find a way to enjoy this superfood that fits your lifestyle.

Conclusion
In conclusion, 100g of spinach is equivalent to approximately 3.53 ounces. The most significant factor to consider beyond this direct weight conversion is the state of the spinach—raw or cooked—which impacts its volume, texture, and nutrient bioavailability. For precise measurements, especially in recipes, a kitchen scale is recommended. Regardless of whether you prefer it raw in a salad or cooked in a dish, incorporating this nutrient-rich leafy green into your diet offers a variety of health benefits.
