I'm trying to work out the volume of my freezer. It measures 37cm x



38cm x 72cm.

Whats that in litres?



I keep trying to work it out & get silly figures.



1 Litre is 1000 cubic centimetres.

You have 37 x 38 x 72 = 101232 cubic centimetres

i.e. 101.2 litres

A litre is a cubic decimetre, so 3.7x3.8x7.2.

Nope = A litre of water has a mass almost exactly equal to one kilogram. An early definition of the kilogram was set as the mass of one litre of wat er. Because volume changes with temperature and pressure, and pressure uses units of mass, the definition of a kilogram was changed. At standard press ure, one litre of water has a mass of 0.999975 kg at 4 °C, and 0.997 k g at 25 °C.[7]

Eh?

You have introduced (a) water and (b) mass quite unnecessarily. The litre was, as you say, formerly defined in terms of a mass of water. But that ended in the 1960s. And is totally irrelevant to the fact that

1 litre is 1,000 cc.

And while cc is a unit from the CGS system it is still widely used in practice and accepted within the SI world.

1000 l = 1m3

So 0.37 x 0.38 x 0.72 / 1000

:)

Very sensible these metric measurements

So 0.37 x 0.38 x 0.72 x 1000

but gettting the decimal point in the wrong place can be a disaster

That's a million times better [sorry Tim].

Simon Mason's reply reveals an interesting character flaw. His craven desire to display display esoteric knowledge meant that in his haste to post, he completely overlooked the question that needed to be dealt with.

In my defence it is early in the morning.

Anytime before 11am is early!

That's what I got, but it's the equivalent to 4 x 25 litre drums - which clearly wouldn't fit, hence I thought it was wrong.

I'm looking for a fridge freezer with a bigger freezer & smaller fridge, so trying to visualise the capacity figures which are given in litres.

I guess I'll have to measure each drawer.

101.232 (= 37 x 38 x 72 / 1000)

It's 4 x 25 litre drums of bubblewrap, which you can squish into the cavity once you've removed all the drawers, shelves and refrigerated pipework and popped all the bubbles ... oh hold on ...

AO do give total capacity in 'bags of shopping' but trying to find anything with more freezer than a 50/50 split is probably impossible. I want one too.

and a litre is 1000cc.

Oh I like it! A 'bag of shopping' becomes the standard unit of volume for the housewife! A bit like 'a banana' becomes the standard unit of a dose of radioactivity.

Lots more bizarre units of measurement on these links. I like the FFF system (furlong/firkin/fortnight)

Think in terms of 20 x 5 litre cans of oil or containers of milk
