"kg/dm?" might be more precise. (The "3" should be superscript of course but I'm far too dumb to work out how to make it go up there!)

That better?  :

Almost right mudman - but kg not "Kg".

Marysboy is of course right.

Nice one Laurie (you clever beggar!).

Litres are an SI accepted unit of volume equal to 1 cubic decimetre (dm3).

So 1 L of rain weighs 9.807 N at standard pressure and temperature.

So one pint (or gallon) weighs what in pounds and ounces?

Damn. Out-pendanted.  :-\

And bugger, pressure, not density. Long time since my physics days.

Never mind that - it's what a pint costs that counts!  :

Awkward *%!&*!

OK, 1 Ltr of rain weighs 1 Kg no matter how heavy it gets.  :tease:

But does it if it's actually "heavy water" - D2O?

The molecular weigh of water is 18 (oxygen (16) + 2 hydrogen (1)). Deuterium has a molecular weight of 2 so D2O 1s 20/18 times as heavy as H2O. (No doubt that will be contradicted by someone that knows at more than me about this subject).

Heavy water has a density of 1.107 g/cm? so 1 litre will weigh 1.107 kg

An Imperial Gallon (of water) weighs 10 lbs.

Ho hum,

Rain weighs 1Kg/L, no matter how heavy it gets.

And there I was, thinking it was a joke.

How can it be that each year about 400,000 Americans are injured by their bedding or beds. Seriously - what do Americans do in or near their beds?
Another 40,000 Americans are injured by their clothing. Underpants haematoma? Compound pyjama fracture? Or do they just strangle each other with their clothing?
You will no doubt relieved to know that only one American was injured by a moose coming through his windscreen. No doubt the mooses (meese?) of America were also pleased.

Probably shoot each other.

Only at 101.325 kPa & 20 C IIRC  (been a while since I last had to do gravimetric calibration)

Why do shoe-laces only break when you're in a hurry?

 

[mikem]

Because your children / grandchildren always tie them together...?

The Obituary Thread nearly always has a new post in it.
Must deter a lot of potential cavers who only read the headlines.... :doubt:
