1. 10 5-gallon Water Containers


5-gallon water containers are suitable for storing and transporting large quantities of water for various purposes. They’re popular in camping, emergency preparedness, or providing a bulk source of clean drinking water.

They’re an excellent way to understand relatively light weights, such as four kilograms, since they weigh approximately just as much.

But even relatively heavy weights, like in our case, you can refer to ten to get an impression of the heaviness of 40 kilograms.

2. A Standard Cement Bag

Bags of cement can vary depending on the region and manufacturer. So, always check the labels or specifications before using them as reference points.

In the United States, the standard size is usually 94 pounds (42.6 kilograms). 

Although slightly heavier than the weight in question, it is still a good benchmark for 40 kilograms.

3. 19 Standard Bricks

Bricks often go hand in hand with cement bags. So it’s justified that we include them in our list since if you’re familiar with the latter, there’s a good chance you also know one, two, or three things about bricks. 

Similarly to cement, brick sizes vary from country to country, so confirm the standard size in your country before referring to them for various measurements. 

In the United States, a standard one usually weighs 2.05 kilograms, making it a perfect reference for 2 kilograms and other lightweight measurements. 

But if you are familiar with them or can get them in plenty, they can give you a practical understanding of 40 kilograms.

To realize that weight, you need as many as 19.

4. A Female Rottweiler

It may seem bizarre to use dogs as reference points for measurements since their weight can vary based on genetics, diet, exercise, and overall health. 

However, they can give you a good-enough idea if they are healthy since some have a close weight range.

The female Rottweiler is one of the most commonly used in such cases, as although their weight varies, the difference is usually minimal, ranging from 36 kilograms to 41 kilograms.

Other dog breeds you can also refer to include male Bouvier Des Flandres (35-40 kilograms) and female Irish Wolfhound (40.9 kilograms).

5. 8 Gallons of Paint

Depending on factors like the type of paint, surface texture, and the number of coats required, the area that 8 gallons can paint can vary.

It is still a generous quantity, considering it weighs as heavy as 39 kilograms (remember, a gallon is approximately 11 kilograms).

If you’re familiar with the weight of one gallon, 40 kilograms is thus about eight times as heavy.

6. 2 Typical Twin-size Mattresses

Twin-size mattresses are suitable for bedrooms with limited spaces, including children’s bedrooms, guest rooms, dorm rooms, and daybeds.

They typically measure 38 inches by 75 inches (96.5 cm by 190.5 cm) and weigh from 40 to 45 pounds (approximately 20 kilograms) depending on the nature of the materials. 

That means 40 kilograms is comparable to the weight of two such mattresses.

7. 2 Average-sized E-bikes

E-bikes, or electric bicycles, have gained popularity recently for several reasons, including being environmentally friendly, convenient, and cost-effective.

Thanks to the batteries and motors, they are heavier than regular bicycles, ranging from 20 to 25 kilograms, depending on the manufacturer and model.

If you own one (or a friend does), you can compare 40 kilograms to the weight of two for a good-enough idea.

8. 3 Mountain Bikes

On the same topic of bikes, you can refer to mountain bikes instead to understand how heavy 40 kilograms is. 

Mountain bikes, however, although heavier than traditional bicycles due to frame material and other components, are slightly lighter than E-bikes, typically weighing between 12 and 13 kilograms.
