DO NOT BUY A WASHING MACHINE until you watch this video

I am often interested in: what is the correct loading of the washing machine, how much laundry needs to be loaded into the washing machine. But I have not found answers to these questions anywhere. Therefore, I decided to offer my version of the answers. I am sure it will be very useful for those who want to buy a washing machine. Especially if it should be a narrow washing machine!
The formula for calculating the load, in kilograms, of a washing machine:
D * D * H * 0.314 / 4000 = KG
Where: D = drum diameter in cm .; H = drum depth in cm .;
For example, a drum diameter of 45cm and a depth of 30cm. Then:
45 * 45 * 30 * 0.314 / 4000 = 4.77 KG
