Volumetric weight script

Hello,

I'm looking for a simple script that will calculate the Volumetric weight of a box and for a tube.
All weights should be rounded off upwards. When possible in "cm" to "kg"
It has to be a simple 1 since I'm not so good with javascripting

please help me out.

regards,
Martijn

Hi

Below are two functions to calcumate the volumetric weight of a box and a tube and examples of how to call them.

The scripts work in cm to kg.

<script language="javascript">

alert(weightBox(100,100,100));

alert(weightTube(100,100));

  function weightBox(intLen, intWid, intHei)
  {
    return Math.round((intLen * intWid * intHei) / 6000);
  }

  function weightTube(intLen, intWid)
  {
    return Math.round((intLen * ((intWid/2 * intWid/2) * Math.PI)) / 6000);
  }

</script>

Cheers

Scott

Something like this?

The script is in the head of the following HTML doc, and it's called calc().  I used the following formulae for volumetric weight:

BOX:  l*w*h / 6000
TUBE: l*w / 6000

(and by tube, I assume you mean shipping tube...)

=== code ========================================
<html>
<head>
<script>

function calc()
{
      var length = document.f.l.value;
      var width = document.f.w.value;
      var height = document.f.h.value;

      if ( document.f.type[0].checked == true ) {
            if ( length > 0 && width > 0 && height >0 )
                  document.f.ans.value = length*width*height/6000;
            else
                  document.f.ans.value = 0;
      }
      
      else {
            if ( length > 0 && width > 0 )
                  document.f.ans.value = length*width/6000;
            else
                  document.f.ans.value = 0;
      }
}

</script>
</head>
<body onLoad="">
<form name="f">
      <input type="radio" name="type" checked>Box
      <input type="radio" name="type">Tube
      <br>
      <input type="text" name="l" size="5">Length (cm)
      <br>
      <input type="text" name="w" size="5">Width (cm)
      <br>
      <input type="text" name="h" size="5">Height (cm)
      <br>
      <button onClick="calc();">Calculate</button>
      <br>
      Volumetric Weight (kg):
      <input type="text" size="20" name="ans" disabled>
</form>

</body>
</html>
=== end code =====================================

Whoops - use this calc function...  Didn't see the rounding requirement...

function calc()
{
     var length = document.f.l.value;
     var width = document.f.w.value;
     var height = document.f.h.value;

     if ( document.f.type[0].checked == true ) {
          if ( length > 0 && width > 0 && height >0 )
               document.f.ans.value = Math.round(length*width*height/6000);
          else
               document.f.ans.value = 0;
     }
     
     else {
          if ( length > 0 && width > 0 )
               document.f.ans.value = Math.round(length*width/6000);
          else
               document.f.ans.value = 0;
     }
}

I checked with DHL's website, and they calculate the voumetric weight of a "tube" as (length*width/6000).  Of course, if you mean "cylinder" instead of tube, by which they seem to show a long triangular prism-shape, use (length*(width/2 * width/2) * Math.PI ) / 6000

so (length*(width/2 * width/2) * Math.PI ) / 6000 for a cylinder like on the dhl website??

No - they only had a calculator for a "box" and "tube."  And by "tube" they meant a long triangular prism shape, not a cylinder.  But their formula for international volumetric weight was (volume/6000).  Here's a link:
