HTML calculator (probably dead simple)

[Skunkworks]

I’m after a simple calculator with 3 fields for height, width and length, and a dropdown for CM or MM. I need it to calculate how many whole 20cm cubes will fit into the space given.

I imagine this is one line of code.

Thanks.

Do you want this in HTML/jscript or would any language do?

Probably more complex than you think.

off the top of my head, i'd take 3 variables, divide each by 20cm to make sure you only get whole boxes the multiple them together.

think that would work ok. but then you've got to take in conversions of mm to cm etc

Sorry, should have mentioned, something I can paste into Dreamweaver.

I used to be able to do this stuff years ago.

I don't know javascript but python something simple like this would work if it was only in cm:

height = int(input("Enter the height: ")
width = int(input("Enter the width: ")
length = int(input("Enter the length: ")

print(int((height/20))*int((width/20))*int((length/20)))

    function doit(){
        document.getElementById("out").value = (document.getElementById("X").value/20)*(document.getElementById("Y").value/20)*(document.getElementById("Z").value/20);
    }

Not checking the mm/cm thing, no validation or anything and you have to create the inputs by yourself!

Edit: NVM, sorted now.
