What Does 140 Grams of Sweet Potato Look Like?
Visualizing a specific weight, especially for fresh produce, can be challenging. A 140-gram serving of sweet potato is roughly equivalent to a small to medium-sized sweet potato, depending on its density and shape. For context, a typical medium sweet potato is often cited as weighing around 135 to 150 grams. This means that 140 grams is a very standard single serving.
Size Equivalents for Measurement
When you don't have a kitchen scale, a few handy conversions can help you get close to the 140-gram mark:
- In cups: A cup of diced or mashed sweet potato weighs differently. A cup of cubed sweet potato is roughly 133 grams, making 140 grams slightly more than one cup. A grated cup is closer to 100 grams, so you'd need about 1 and a half cups of grated sweet potato.
- Roughly 4.9 ounces: For those using imperial measurements, 140 grams is approximately 4.9 ounces.
- A small sweet potato: When buying whole sweet potatoes, select one that feels relatively heavy for its size, but is on the smaller end. This is a simple, eyeball method to estimate your portion.
How Cooking Affects Weight
It is important to remember that cooking can affect the final weight. Boiling or steaming can add water, while baking or roasting removes moisture. The nutritional information for 140g of raw sweet potato will differ slightly from that of cooked, but the core macronutrient profile remains largely the same.
