> A fire extinguisher large enough for a 500wh battery weighs 12 kilos - most people can barely lift that!

Almost everyone can lift that overhead. 90% of men and more than 50% of women can lift a bit more than twice that overhead. It's a common job requirement.

There would have to be something really wrong for an adult to struggle lifting 12kg. That's a large watermelon, and unlike the melon, the fire extinguisher got a handle.

Handheld fire extinguishers top out at that weight - because the vast majority of people will be able to use them and it's better to have two than make them any bigger.

Where on earth do you get 12 kg watermelons? Genuine curious, the ones imported here in Denmark I would guess are big if they're around 3 kg.

I get them from my garden but I weigh them in pounds. Larger ones can grow in excess of 40 lbs (close to 20 kg).

Am from the Southeastern United States.

Before making a guess, try to weight them. I have hard time imagining watermelon (watermelon is the green thing unlike yellow melon) with only 3kg :) Your full water kettle already weights 2+kg.

In Istanbul the watermelons we get from the grocery store are about 4kg, the ones we buy from the road-side watermelon trucks in the summer can be 10-15kg (if their scales aren't rigged).

Warmer countries. E.g. in Italy the common water melons are at least half a meter long.

Sitting even further north than Denmark, the OP did say that their melons are imported. Although it's possible to grow them in Denmark (especially in a greenhouse) perhaps it's not commercially viable.

Regardless, I guess the OP just needs to find a better grocer, local "fruit mongers" up here in frigid Sweden certainly routinely handle watermelons that are way bigger than 3 kg. :)

The same in Portugal. Ours can be very big.

I guess we can conclude a watermelon is a really bad weight reference unit!

Is there anything "units" can't convert?
