# 11 Everyday Things That Weigh 90 Pounds

Last updated on May 14th, 2022 at 01:30 pm

Ninety pounds is a relatively common measurement, especially when it comes to estimating the weight of items.

However, it can be very challenging to get a real feel for just how much weight that is if you don’t have anything to compare it to.

## 11 Gallons of Water

A gallon of water weighs roughly 8.3 pounds. You would need about 11 gallons of water, therefore, to equal about 90 pounds.

You can also use other common household drinks, such as soda or milk, to equal around 90 pounds.

However, it’s important to remember that the density of a liquid affects how much it weighs. Denser liquids weigh more.

For example, a gallon of milk weighs about 0.3 pounds more than a gallon of water because milk is denser than water. Temperature can also affect how much a gallon of water weighs.

Warm water is less dense than cold water, so you can technically put more cold water into a gallon container than warm water.

Since you’re adding more water, cold water will weigh slightly more than warm water.

## 3 Collies

Collie dogs, such as the dog that played Lassie on television, are easily recognizable.

Although each dog of this breed grows to a slightly different size, most rough-coated collies weigh between 44 and 75 pounds, therefore two of these dogs in the lighter range would weigh very close to 90 pounds.

Border collies, which are similar in appearance to rough-coated collies but have black and white markings and are smaller in size, usually weigh around 30 pounds, so three border collies would equal about 90 pounds.

## 3 Small microwaves

Microwaves are available in many different sizes. Small microwaves, which can be found in small kitchens, can weigh as little as 30 pounds. Three of the same sized microwaves will equal 90 pounds.

However, larger microwaves, such as those that might be found in a large family home with a big kitchen, or the type that might be used in a kitchen at a restaurant, often weigh closer to 60 pounds.

So you would need more than a single large microwave to equal 90 pounds.

## 3 Box Spring Mattresses – twin size

A box spring mattress is the sturdy, nearly hard mattress that goes underneath the mattress you sleep on.

A box spring provides stability and support, increasing comfort and prolonging the life of your mattress.

A queen-sized box spring can weigh between 60 and 105 pounds.

A box spring for a twin mattress, on the other hand, usually weighs around 30 pounds, so you would need three to equal about 90 pounds.

## 3 Small Flat-Screen TVs

How much a flat-screen TV weighs depends on the TV size. Smaller TVs can weigh as little as 25 pounds, while larger TVs can weigh up to 75 pounds.

CHECK OUT  How Long Is 2 Inches Compared To An Object?

A TV with a screen that’s about 50 inches will weigh around 45 pounds, so two of these TVs will weigh 90 pounds. If you add in the stand or the brace for attaching it to the wall, the tv will weigh more.

Smaller TVs with screens of around 32 inches usually weigh a little less than 30 pounds, so three of these TVs would equal about 90 pounds.

## 9 Cats

The breed of a housecat, how it was raised, and whether it’s male or female determines how big it will grow, and each cat grows to a slightly different size.

In general, though, most housecats weigh around 10 pounds. You would, therefore, need nine cats to equal 90 pounds.

## 3 Large Bags of Dog Food

If you have a big dog or you need to feed multiple dogs, you’ve probably purchased large bags of dog food.

Although you can buy dog food bags in a few sizes, one of the most common larger sizes weighs 30 pounds. You would need three of these bags to equal 90 pounds.

## 3 Mountain Bikes

Mountain bikes are designed to be sturdy and durable so they can cross even the roughest terrain, so it makes sense that they would weigh a fair amount.

Usually, a single mountain bike weighs just less than 30 pounds, so three would equal around 90 pounds. Lightweight mountain bikes, however, can weigh closer to 21 pounds.

The heaviest a mountain bike can be is 37 pounds.

## 6 Thanksgiving Turkeys

You can buy a turkey for Thanksgiving or Christmas in a variety of sizes, depending on how many people you need to feed.

The average weight for a whole turkey, however, is around 15 pounds, so you would need six of them to equal 90 pounds.

You can also purchase a whole chicken, although these tend to be significantly smaller than turkeys.

A whole chicken usually weighs between 4 and 6 pounds, so you would need between 15 and 23 whole chickens to equal 90 pounds.

## 9 Sledgehammers

Sledgehammers are very useful for a number of home improvement and construction jobs.

Small household sledgehammers usually weigh about 10 pounds, so nine hammers would equal 90 pounds. Visualizing a standard sledgehammer can help you break 90 pounds down into even increments.

Some larger sledgehammers, particularly those used for tasks such as breaking up concrete, can weigh more than double what a household sledgehammer weighs.

In this case, you would only need four large sledgehammers to equal around 90 pounds.

## 3 Cinder Blocks

You can find cinder blocks in a few different sizes, as they can be used for different construction tasks.

A cinder block’s weight is determined by its overall size, but most cinder blocks weigh between 28 and 35 pounds.

This means that three cinder blocks would weigh right around or just over 90 pounds.
