In various industries, ranging from manufacturing to packaging, understanding and being able to convert different units of measurement for material thickness is essential - common units used for this purpose are gauge, micron, and millimetre. Whether you're dealing with polythene films or other materials, having a reliable conversion guide can streamline processes and ensure accuracy in measurements.
Polythene gauge (ga) can be converted to micron (mu) by dividing it by 4, and the thickness in millimetres (mm) can be determined by dividing the micron value by 1000. An example of this would be 50mu equalling 200ga, which is equivalent to 0.05mm.
The thickness of your polythene can range from ultra-light (typically between 32-50ga) to super heavy (1000-1200ga), so it is important to make accurate calculations.
Our conversion table below states how each measurement converts to another, enabling you to make informed decisions and perform accurate measurements with confidence.
Gauge (ga) | Mil | Inch (in) | Micron (mu) | Millimetre (mm) | Centimetre (cm) |

Micron and gauge measurements are used to determine the thickness of materials in a number of different industries, whereas millimetres, metres and inches are used more commonly in everyday life.
Micron and gauge measurements are extensively used in the packaging industry to determine the thickness of materials such as plastic films, shrink wraps, and packaging foils. These measurements are crucial for ensuring the durability and protection of packaged goods.
Micron and gauge measurements are also used in the manufacturing industry, to specify the thickness of materials such as metal sheets, rubber, textiles, and various types of films.
In the packaging industry, accurate conversions are important for ensuring that the quality of your packaging is up to standard. If the thickness of your film falls below the correct specifications, this can lead to packaging failures, such as splitting, bursting or leaking, meaning it is less effective at protecting goods. Also, plastic packaging materials that do not meet the correct thickness specifications (for example, material that is stretched too thin during the packaging production process) can be less effective at blocking oxygen and other contaminants, potentially causing rapid product degradation.
