Conver paper weight from pounds (lbs) to gramms
var a_baseFormats = {
'bond' : '17 x 22',
'bristol' : '22.5 x 28.5',
'card stock' : '20 x 26',
'cover' : '20 x 26',
'index' : '25.5 x 30.5',
'newsprint' : '24 x 36',
'tag' : '24 x 36',
'text' : '25 x 38',
'writing' : '25 x 38'
};
function f_getGramWeight (s_poundWeight) {
if (!s_poundWeight.match(/^(d+)(?:lb)?s+(.*)$/i)) return '?';
var n_weight = parseInt(RegExp.$1);
var s_baseFormat = RegExp.$2;
var s_baseSize = a_baseFormats[s_baseFormat.toLowerCase()];
if (!s_baseSize || !s_baseSize.match(/^([d.]+)s*xs*([d.]+)$/i)) return '?';
var n_width = parseFloat(RegExp.$1);
var n_height = parseFloat(RegExp.$2);
return Math.round((n_weight * 1406.5) / (n_width * n_height));
}
accepted values are in format like "80lb card stock"
