Polythene film thickness conversion
Plastic sheeting, tubing and bags are measured by their thickness and is expressed in gauge (imperial) or microns (metric).
Gauge relates to thickness. Each 100 gauge is 1 thousandth of an inch.
Microns are thousandths of a millimeter.
Gauge can also be related to microns by dividing the gauge by 4.
