Knowing things that weigh about 90 pounds can have practical applications in areas such as fitness, travel, shipping, DIY projects, and education.
They can also be a fascinating way to learn about the world around you, while you can use them as comparisons if you have varied interests.
So, to help you solve practical problems and make informed decisions regarding the weight of 90 pounds, this post explores 15 items weighing approximately as much so you can use them as reference points.
Read on to find what items suit your pursuits.
15 Common Things That Weigh About 90 Pounds
Objects or entities weighing 90 pounds are typically moderately heavy in everyday life.
Although they are generally manageable with proper handling, they still require some effort, particularly if they need to be lifted or moved.
1. 11 Gallons of Water
Water is an excellent way to understand different weights, from featherlight as one ounce to as heavy as 100 kilograms. It’s available almost everywhere, and even better, you can divide it into different quantities, i.e., teaspoons, tablespoons, or gallons, to determine various measurements.
For 90 pounds, the most sensible way is to go with gallons.
So, since a gallon weighs 8.34 pounds, you can compare 90 pounds to eleven gallons of water, and you can’t go wrong.
2. 10.5 Gallons of Milk
Milk, similarly to water, is a reliable reference point for different weights since you can subdivide it into different quantities to suit what you want to determine.
For a weight as heavy as 90 pounds, you can compare it to as many as ten and a half gallons of milk since each weighs 8.6 pounds in the United States.
Ten and half a gallon is a substantial quantity of milk, suitable for catering events or commercial food preparation.
3. 8 Gallons of Paint
The weight of a gallon of paint can vary depending on the type and brand of paint and its specific formulation.
That said, on average, a gallon of paint typically weighs 10 to 12 pounds.
Thus, 90 pounds is comparable to about eight gallons. That’s enough for larger painting projects or multiple rooms, considering one gallon of paint can cover approximately 350 to 400 square feet.
4. 20 Standard Bricks
Standard bricks typically have uniform dimensions.
In many countries, including the United States, the standard brick size is about 8 inches and weighs about 4.5 pounds, making it a good reference for things that weigh about four pounds and other relatively light measurements.
But if you can get them in plenty, say twenty, they can be a reliable benchmark for 90 pounds.
5. A Standard Bag of Cement
Similarly to bricks, bags of cement vary in weight from country to country.
For example, a standard bag usually weighs 94 pounds in the United States.
It’s slightly heavier than 90 pounds, but it can still be a reliable reference for that weight, depending on your interests and needs.
6. 2 Typical Twin-size Mattresses
Twin-size mattresses are ideal for children, teenagers, or adults who prefer sleeping alone. They are popular in children’s bedrooms, bunk beds, daybeds, and guest rooms.
These mattresses are 38 inches wide and 75 inches long and weigh between 40 and 45 pounds. The weight variation is due to the materials used – memory foam, innerspring, latex, and hybrid models.
Two such mattresses would clock about 90 pounds.
7. 3 Typical Mountain Bikes
Mountain bikes are popular for recreational riding, trail exploration, and even competitive mountain biking.
They come in various styles, including hardtail and full-suspension models, each suited to different trails and riding preferences.
However, since the different subtypes share most features, such as sturdy frames, wide tires with deep treads for better traction on rough terrain, and suspension systems, they weigh almost the same, with a weight range of 28 to 32 pounds.
If you’re a regular mountain biker or are familiar with them, you can imagine how heavy three bikes would be. That’s about 90 pounds.
8. 6 Small Passenger Car Tires
By small passenger car tires, we mean those designed for compact and midsize passenger vehicles, including sedans, coupes, hatchbacks, compact SUVs, and crossovers.
Although small passenger car tires come in various sizes, usually specified in numbers and letters on the tire sidewall, the average weight is approximately 15 pounds.
Thus, you can equate 90 pounds to the weight of six such cars to understand how heavy it is.
9. 2 Bushels of Apples
A bushel is a unit of volume that can hold varying amounts of apples, depending on the size of the apples and how you pack them.
It typically contains about 45 pounds of the fruits, meaning two such bushels are about 90 pounds heavy.
With such a huge quantity of apples, you can create delicious treats, from traditional apple pies to more adventurous dishes like apple crisps, tarts, and apple butter.
10. 2 Bushels of Grapes
A bushel of grapes is slightly heavier than a bushel of apples, at approximately 47 pounds.
But still, two can give you a practical idea of 90 pounds, as they are only four pounds beyond that weight.
11. 18 Reams of Letter-sized Papers
A ream of letter-sized paper is a standard and convenient unit for purchasing papers commonly used in offices, schools, and businesses for printing and documentation purposes.
Each ream typically contains 500 sheets of this commonly used paper size and is precisely five pounds heavy.
Although it’s ideal for determining relatively light weights starting with five pounds, you can rely on them for heavy weights, like in our case here, especially if you regularly interact with them.
To do so, you can imagine lifting as many as 18 reams at once.
12. A Female Rottweiler
Rottweilers have distinctive black coats with tan markings on their face, chest, legs, and paws. They are intelligent dogs and are known for their problem-solving abilities.
They are medium-sized dog breeds with a powerful and muscular build. Females are lighter than males, weighing up to 41 kilograms or approximately 90 pounds.
13. A Male Bloodhound
Bloodhounds are large, heavily built dogs with loose, wrinkled skin and long, pendulous ears.
These dogs are known for their strong tracking instincts, making them excellent working dogs in law enforcement and search and rescue teams.
Males weigh approximately 90 pounds.
14. 2 Japanese Akita
Japanese Akita, also known as the Akita Inu or Akita Ken, is a noble and powerful breed of dog originating from Japan. It has a characteristic large, robust body with a dignified and imposing appearance.
Unlike many other dog breeds, male and female Japanese Akita weigh almost the same, about 45 pounds.
If you’re familiar with them, 90 pounds is twice as heavy as these dogs.
15. 9 Domestic Cats
Domestic cats can vary widely in weight, depending on breed, age, gender, and individual health. They can be as heavy as 25 pounds, such as the Maine, and as lightweight as five pounds, such as Siamese.
That said, the typical domestic cat found in most households weighs about ten pounds.
Therefore, if you put nine such cats on a scale, it would tip close to 90 pounds.
