One hundred grams, which is about .22 pounds or 3.5 ounces, is a very small amount of weight, so it can sometimes be difficult to guess just how much it is.

Knowing how to estimate 100 grams, however, can come in handy for measurements, when calculating calories in certain foods, or when trying to calibrate a scale.

There are, fortunately, several common items that weigh about 100 grams.

## #1. Four AA Batteries

Batteries are a common household item, and AA batteries are perhaps the most common type people can find lying around.

Each of these batteries weighs about 24 grams, so four AA batteries together equals 96 grams, very close to the 100-gram mark.

This exact weight can help you easily calibrate a small digital scale.

## #2. A Medium Tomato

Tomatoes are often quite heavy for their size, as they’re mostly made up of water and contain a good amount of juice.

Although large tomatoes can often weigh quite a bit more, a medium-sized tomato, such as the one you might slice up to add to a sandwich, salad, or to top a burger with, weighs about 100 grams.

Holding a tomato of this size in your hand can give you an accurate feel for the weight of 100 grams.

You might also be able to find other fruits or vegetables that weigh about 100 grams.

Half of a pomegranate, for example, which is denser and slightly larger than a medium tomato, weighs about 100 grams.

Similarly, half of a regularly sized apple weighs about 100 grams, while a whole banana will be close to 100 grams.

Other food items also weigh about 100 grams, and this knowledge can come in handy when cooking or baking.

For example, a stick of butter, which is about half a cup, weighs just over 100 grams, at 113.

A cup of almonds or half a cup of uncooked rice also weighs almost exactly 100 grams, depending on the size of the almonds or the type of rice.

## #3. Two Pieces of Silverware

There are many different types and styles of silverware, and table wear can be made from many different materials.

This means that silverware can vary greatly in weight. However, everyday silverware made from silver or steel has an average weight of about 50 grams per piece.

Larger pieces, such as knives or large dinner forks, might weigh a little more, while smaller pieces, such as tablespoons, weigh a little bit less.

To even this out, grab a dinner fork and a tablespoon and you’ll have just about 100 grams in weight.

## #4. A Small Jar of Spices

If you’ve ever visited the spice aisle at your local grocery store, you’ve probably seen the small jars of spices lined up on racks.

Although spices themselves vary greatly in density and weight, most of these spices are sold by the ounce, so each small jar weighs about the same.

The jar, plus the spices inside, usually weighs right around 100 grams.

If you’re trying to get a feel for what 100 grams is, or if you want to check to make sure a scale is still calibrated properly, reach into your pantry and grab a small jar of spices.

## #5. A Bar of Soap

An average-sized bar of soap is about 100 grams. Most people are familiar with how heavy a bar of soap feels in the hand, and there’s usually a bar of soap somewhere around the house, so this is a great way to estimate the weight and feel of 100 grams.

Of course, different soaps include different ingredients, and bars may be shaped differently, so the exact weight can vary slightly from bar to bar.

## #6. A Small, Newborn Puppy

Because dogs can grow to such a wide range of sizes, puppies are, logically, also born at a variety of different sizes and weights.

However, many dog breeds have newborn puppies that weigh about 100 grams. When estimating how much 100 grams is, think of a newborn puppy from a small breed such as a terrier or a chihuahua.

Other baby animals also weigh right around 100 grams.

Very young kittens, for example, are about 100 grams, so if you’ve ever held a young kitten, you can estimate what 100 grams feels like in the hand.

## #7. A Box of 100 Paperclips

A single, regularly sized paper clip weighs almost exactly one gram.

Therefore, a standard box of 100 paperclips weighs almost exactly 100 grams.

With the box included, the weight might be a few grams over 100, but this is still a very accurate way to estimate how much 100 grams is and one of the most accurate ways to calibrate a digital scale.

## #8. Forty Pennies

Coins are surprisingly heavy for their size, and even a penny weighs about two and a half grams.

Forty pennies, piled together, weigh about 100 grams. Most people have a few pennies around the house, so this is an accurate way to estimate how much a gram or 100 grams is.

You can also use other coins to estimate how much 100 grams is.

Quarters, for example, weigh slightly more than five and a half grams each, so 17 or 18 quarters will get you to just below or just above 100 grams in weight.

Nickels weigh exactly five grams, so if you pile together 20, you’ll have 100 grams.

## #9. Twenty-Two Pieces of Paper

Standard printer paper, which measures eight by 11 inches, weighs four and a half grams per sheet.

This means that if you stack 22 sheets together, you’ll have 99 grams, very close to the goal of 100 grams.

Holding this many sheets of paper together can give you a very accurate idea of the weight of 100 grams.
