# How much Cal is half a watermelon?

Half a watermelon contains a significant amount of calories and nutrients. Determining the exact calorie count requires looking at the average size and nutritional information for watermelons.

On average, half a medium-sized watermelon with edible flesh of 800 grams or 1.76 pounds contains about 270 calories.

## Calculating Watermelon Calorie Count

To estimate the calories in half a watermelon, we need to know:

• The average weight of a medium or large watermelon
• The approximate amount of edible watermelon flesh
• The calorie content in a gram or ounce of watermelon flesh

Let’s look at each factor in detail.

### Average Watermelon Weight

According to the United States Department of Agriculture (USDA), the average weight of a medium or large sized whole watermelon is:

• Medium – 13 to 18 pounds
• Large – Over 20 pounds

For simplicity, let’s estimate the average medium watermelon weighs around 15 pounds.

### Edible Watermelon Flesh

However, the entire 15 pound weight is not edible flesh. The rind, seeds and non-fleshy parts are inedible.

According to estimates, around 65% of the total weight of a watermelon is edible flesh. The rest is rind and seeds.

So if we take a 15 pound medium watermelon, about 65% of 15 pounds is edible flesh. That comes out to around 9.75 pounds of edible watermelon flesh.

### Calories in Watermelon Flesh

Now that we know the average weight of edible watermelon flesh, we need to determine the calories in watermelon per pound or per gram.

Here is the calorie content in watermelon flesh:

• Per 1 pound – 140 calories
• Per 100 grams – 30 calories

This nutritional data is from the USDA FoodData Central database.

### Calculating Calories in Half a Watermelon

We have everything we need to determine the calorie count in half a watermelon!

For a 15 pound medium watermelon:

• Edible flesh weight = 9.75 pounds
• Calories per pound = 140 calories

Since we want to know the calories in half the edible flesh:

• Half of 9.75 pounds is 4.875 pounds
• With 140 calories per pound, calories in 4.875 pounds is 4.875 * 140 = 682 calories

We can also calculate the calories by grams:

• 9.75 pounds is 4435 grams (1 pound = 453.5 grams)
• Half of 4435 grams is 2217.5 grams
• With 30 calories per 100 grams, calories in 2217.5 grams is 2217.5 * 30/100 = 665 calories

So for half a medium 15 pound watermelon, the calorie count comes out to between 665 and 682 calories depending on the method of calculation.

## Typical Serving Size of Watermelon

Now that we know the calories in half a watermelon, it’s also useful to look at typical serving sizes people may consume.

Here are some common serving sizes for watermelon flesh and their calorie counts:

Serving Size Grams Calories
1 watermelon wedge or slice 280g 84
1 cup watermelon balls 150g 45
1 cup diced watermelon 152g 46

As you can see, people typically consume watermelon in servings of around 1 cup or less. A single serving has between 45-85 calories.

This makes watermelon great for hydration. It can help you stay hydrated on hot summer days.

## Choosing the Best Watermelon

Picking a juicy, sweet watermelon can take some skill. Here are some tips for choosing the best watermelon:

• Choose a heavy melon for its size. Heavy means more water content.
• Look for a yellow/cream/white spot on one side. This means it sat on the ground and ripened.
• Check the rind for bruises, dents or cuts. Avoid melons with these.
• Look for a smooth symmetrical shape with no irregular lumps or bumps.
• Rind should be dull, not shiny. Shiny means underripe.
• Press rind with thumb. It should dent slightly when ripe.

## Cutting a Whole Watermelon

Follow these steps for cutting a watermelon into wedges, slices, cubes or balls:

1. Wash the watermelon thoroughly under water before cutting.
2. Place the melon on a clean cutting board or counter.
3. Slice off both ends to create flat surfaces.
4. Stand the melon upright and slice down the center to cut into two halves.
5. Lay each half flat side down to cut into wedges or slices.
6. Remove rind and cut fruit away from rind.
7. Cut wedges, slices or cubes as desired.
8. Scoop out any seeds.
9. Store cut melon refrigerated.

Be sure to use a sharp knife and clean cutting board for easiest slicing and dicing.

## Storing Leftover Watermelon

Properly stored, cut watermelon lasts 3-5 days in the refrigerator. Follow these storage tips:

• Store cut watermelon in an airtight container.
• Press plastic wrap directly on the surface of cut fruit.
• Place container in crisper drawer of fridge.
• Consume refrigerated watermelon within 3-5 days.
• Cutting it into smaller pieces helps it last longer.
• Freeze pureed watermelon in ice cube trays for smoothies.
