Is height in cm really four times the weight in kg?

[another-view]

of what???

[pamdang]

an object

[kempie]

Which object?

A human of height 180cm (5'11") would need to weigh 45kg (99lbs or 7st 1lb).

Ok, then the answer would be no, because it would depend on the object. Thanks!

I�ve not come across this approximation before, but my calculations show that:-

An 80kg person would be 2 metres tall, and have a BMI (Body Mass Index) of 20.

A 70kg person would be 1.75 metres tall, and have a BMI of 23.

A 60kg person would be 1.5 metres tall, and have a BMI of 27.

(BMI = weight in kg, divided by height in metres squared)

So I guess you could take it as a crude approximation.

Of course it depends on the object. A balloon could be 30cms high but certainly won't weigh nearly 8kg. A manhole cover is only a few cm high but weighs much more.

Weight in kg implies mass. Mass implies volume. There is no volume to be derived from a single linear measurement in cm.

No, sorry Pam....

Yes - always.

Just like the speed of a car on the motorway is always one eighth of your electricity bill in kWh (kiloWatt hours),

... which is equivalent to 6 football pitches x the specific heat capacity of liquid carbon dioxide in Joules per kilogram per Kelvin.
