15 Common Things That Weigh About Half a Gram

1. A Raisin

One raisin alone can’t satisfy hunger or provide significant nutritional benefits – it’s too little to make a difference.

However, it’s all you need to understand how lightweight half a gram is since it’s just as heavy.

They’re popular additions in many dishes, from oatmeal and salads to cookies and trail mix, while some people use them as standalone due to their sweet and chewy texture.

2. 2 Pumpkin Seeds

Did you know that pumpkin seeds have been one of the humans’ favorite snacks for as far back as 7,000 to 5,500 BCE?

And all that is because of their rich nutritional profile, boasting loads of protein, healthy fats, fiber, vitamins (like B vitamins), and minerals (such as magnesium, zinc, and iron).

Each pumpkin seed weighs approximately 0.3 grams, including the kernel, meaning two will be about 0.5 grams. 

The recommended serving is about 60 seeds (a quarter cup), according to The American Heart Association, so do not go beyond that just because you find them tiny.

3. A Sunflower Seed

Similarly to pumpkin seeds, sunflower seeds are nutritious snacks with many benefits, including supporting heart health and providing antioxidants.

These seeds are almost double as heavy as pumpkin seeds, as they weigh 0.5 grams, excluding the kernels.

While consuming them, limit yourself to only 30 seeds or about a quarter cup.

4. 2 Corn Grain Kernels

Corn grains, also known as maize, are a widely cultivated cereal crop with a rich history dating back thousands of years. They’re essential in many cuisines worldwide while playing a vital role in global agriculture. 

Corn grain kernels are in the same class as pumpkin seeds, as they have a mass of between 0.25 and 0.3 grams, depending on the variety.

That means you can compare 0.5 grams to two corn grain kernels.

5. 8 Wheat Grains

Wheat grains are a staple food source for millions of people worldwide. They are a significant source of carbohydrates, dietary fiber, and essential nutrients, including vitamins and minerals.

As expected, wheat grains are featherlight compared to the other seeds we’ve seen,  weighing only 0.065 grams.

Thus, to weigh 0.5 grams, you want to have about eight.

6. Two Peas

Dried peas can be ground into pea flour and used in various recipes, such as soup or gluten-free baking.

They are as heavy as pumpkin seeds and corn grains, weighing approximately 0.25 grams on average.

So, you would need two to understand how lightweight half a gram is.

8. Half a US Dollar Note

United States dollar notes are an excellent way to understand lightweight measurements, starting from one gram to 10 grams. That’s because they’re readily available and have standard sizes. 

Regardless of the denomination, all US dollar notes weigh the same, precisely one gram. 

So, if you have one right now, place it on your hand and imagine something half as heavy. That’s how 0.5 grams feels like.

9. A 1×1 Inch Lego Brick

Lego bricks are a popular and versatile toy known for their interlocking design, allowing endless possibilities for creativity and building.

Lego bricks come in various sizes and shapes to accommodate different building needs and styles.

1×1 inch bricks are one of the most common and are perfect references for half a gram since they weigh 0.45 grams, which is close.

Their low weight makes them easy to handle while minimizing the risk of injuries during play.

10. Half a Standard Post-it Note

Post-it notes are adhesive paper notes commonly used for temporary notes, reminders, and organization. Their ability to stick to various surfaces without leaving residue makes them a handy tool for personal and professional use.

Post-it notes come in different sizes, from featherlight ones weighing 0.02 grams to standard ones measuring 3×3 inches and weighing approximately one gram.

So, using the standard ones as benchmarks, 0.5 grams is half their weight.

If you have many or don’t mind, you can tear one into equal parts. Each part should weigh 0.5 grams.

Aspirin is a widely used medication known for its pain-relieving (analgesic), anti-inflammatory, and fever-reducing (antipyretic) properties.

You can get aspirin over the counter, but if you have any questions or concerns about their uses beyond using them for weight comparisons, consult a medical professional for guidance.
