10 Things That Weigh 300 Grams
Two MLB Regulation Baseballs
Each official baseball weighs 142 to 149 grams, per MLB Rule 3.01. Two together land right at 284 to 298 grams — practically 300 grams.
Rawlings, the exclusive MLB supplier since 1977, targets an internal production weight of 145–149 grams per ball. If you have ever tossed a baseball at the park, two of them stacked in your palm is almost exactly what 300 grams feels like.
A Standard Campbell’s Condensed Soup Can
A Campbell’s Condensed Chicken Noodle Soup — the classic 10.75 oz can — weighs approximately 305 to 310 grams including the aluminum shell and contents.
Two Medium Fresh Apples
According to USDA nutritional data, a standard medium apple weighs roughly 150 to 182 grams. Two medium apples — Gala, Fuji, or Honeycrisp — combine for 300 to 364 grams.
Three Medium Bananas
The USDA FoodData Central lists a medium banana at approximately 118 grams. Three medium bananas combine for 300 to 354 grams.
It is especially useful for meal prep, smoothie portioning, and calorie tracking — three bananas give you roughly 315 calories and 27% of your daily potassium.
Two Boneless, Skinless Chicken Breasts
The average medium boneless chicken breast weighs 150 to 174 grams per the USDA. Two medium breasts together equal approximately 300 grams of raw protein.
For anyone tracking macros, 300 grams of chicken breast delivers roughly 60 to 66 grams of protein depending on fat content. It is a fitness community staple measurement.
300 Grams of Raw Ground Beef
Measured raw on a kitchen scale, 300 grams of ground beef equals exactly 10.5 ounces. That is enough to make two to three standard burger patties.
The USDA notes this amount provides roughly 60 to 70 grams of protein depending on fat percentage (80/20 vs 93/7). Visually, it forms roughly a baseball-sized ball when shaped — connecting two entries on this very list.
A Compact Tablet Device
Apple’s iPad Mini 5th Generation (Wi-Fi) weighs exactly 300.5 grams per official Apple specifications. That is one of the most precise matches on this entire list.
Many 7 to 8-inch Android tablets also fall within the 280 to 320-gram range. If you own a compact tablet, there is a strong chance you are already holding about 300 grams of technology every time you pick it up.
Cased Flagship Phone
The iPhone 15 Pro Max weighs 221 grams on its own. Add a standard protective case — typically 50 to 80 grams — and your total reaches 271 to 301 grams.
Samsung Galaxy S-series flagships follow a similar pattern. The device most people are reading this article on — with a case — weighs close to 300 grams. It is the most personal, portable reference on the list.
A Standard Paperback Novel
A typical 300-page paperback — the kind you find at airports and bookstores — weighs between 280 and 340 grams, depending on paper stock and binding quality.
Bestselling fiction paperbacks from publishers like Penguin and Simon & Schuster consistently land in this range.
The Adult Human Heart
According to medical literature including the Physics Factbook and peer-reviewed anatomy data on ResearchGate, the average adult human heart weighs between 250 to 350 grams — with 300 grams as the most widely cited average.
Male hearts average closer to 315 grams. Female hearts average around 265 grams. The heart is the size of a clenched fist and beats roughly 100,000 times a day.
How Much Is 300 Grams in the Kitchen?
Without a kitchen scale, knowing how many cups equal 300 grams for common ingredients saves time and prevents baking mistakes. Cup measurements vary by ingredient because density differs.
FAQ’s (Weight 300 Grams)
How many ounces is 300 grams?
300 grams equals 10.58 ounces. To convert, multiply grams by 0.03527. In practical kitchen terms, that is just over 10 and a half ounces — slightly heavier than a standard condensed soup can’s contents.
Is 300 grams equal to 1 pound?
No. One pound equals 453.6 grams. So 300 grams is about 66% of a pound — not a full pound. It is closer to two-thirds of a pound.
What is equivalent to 300g?
In everyday terms, 300 grams is equivalent to two MLB baseballs, a Campbell’s condensed soup can, two medium apples, three medium bananas, or the average adult human heart. In imperial units, it equals 10.58 oz or 0.66 lbs.
How many is 300 grams in a cup?
It depends on the ingredient. 300 grams of water equals about 1.25 cups. Flour equals 2.4 cups. Sugar equals 1.5 cups. Cups measure volume — grams measure weight — so the conversion always changes by ingredient density.
How to convert 300g to oz in a recipe?
Multiply 300 by 0.03527. The result is 10.58 oz. Most digital kitchen scales toggle between grams and ounces directly. If you are working without a scale, 300g ≈ 10.5 oz is a reliable mental shortcut.
