Tank Diameters

[Fighterfish]

Hi,
How many gallons does a 18'' x 11'' x18'' hold? Also how much does a 45cm x 45cm x45cm hold? Thanks

Dimensions I think you mean.

In cm's

LxWxH / 1000 gives you the litres / 3.785 gives you US gallons

In inches

LxWxH /231 gives you US gallons X by 3.785 for litres

1" is roughly 2.54cm aswel.

The 18"x11"x18"= 15.43g or 58.4 litres

45cmx45cmx45cm = 24.09g or 91.13 litres

1" is roughly 2.54cm aswel.

1" is exactly 2.54cm. Unless you're Victorian.

Now, quickly everyone, join hands & lets perform the nit-picking dance.

Well that's what I know it to, thought there was a more precise answer though.

If 1cm if 0.39" though, 1 divided by 0.39 gives you an answer I can't work out in my head. 2.56410256cm's to an inch roughly. Can be even more precise, if you like?

Your maths lesson for the day.

EDIT - to add 1/0.39 = 2.5641025641025641025641025641026. So 2.5641025641025641025641025641026cm to an inch.

Oh, for the love of God...

Mate, I have a bloody Masters degree in Electronics Engineering and I've done enough 'Maths Lessons' to last a lifetime - I tended to go to the ones which taught correct math btw.
I promise you, 1 INCH = 2.54 centibloodymeters. PERIOD.

If 1cm if 0.39" though

But it's NOT!
0.393700787 Inches = 1cm

Fine, have it your way.

So if you right- 0.393700787 Inches = 1cm

1/0.393700787 = 2.5400000025908000026426160026955

And I specialise in maths but the engineer knows more.
