In the imperial and metric systems, I believe you must be very familiar with one of them.
When we express the thickness of sheet metal, especially the thickness of the galvanized sheet, people who are accustomed to using metric systems will use mm as the unit, while those who are accustomed to the imperial system will use inch as the unit.
However, do you know the difference between metric and imperial?
Let’s take a brief look.
It is a measurement system used by English-speaking countries such as the United Kingdom and the United States. Because of various historical reasons, the English system is quite complicated.
But British law stipulates that commercial retail must use the metric system.
In the field of science, the British are used to the metric system, and the Americans are used to the English system.
An international weights and measures system introduced to China after the signing of the Sino-French Business Charter in 1858.
Founded in France.
On April 7, 1795, the French National Assembly decided to promulgate the metric system regulations.
After 1840, the number of countries using the metric system gradually increased.
In 1875, 17 countries signed the metric system convention in Paris, which came into force on January 1, 1876.
Difference: Metric units are measured in millimeters, and imperial units are measured in inches.
Through the above explanations, we know the metric and imperial systems already. In the field of metal processing, for a variety of reasons, some people need to know how they are converted.
For example, an American wants to confirm the required bending force according to the thickness of the sheet metal and the length of the bend, and then buy a press brake machine from China. He must first know how to express the thickness and length of the sheet metal in the metric system, and then the press brake manufacturers are able to calculate the press brake tonnage based on these data.
In order to help you guys who specialized in metalworking industry to check sheet metal gauge to inch and sheet metal gauge to mm, I collect the sheet metal gauge sizes conversion chart (with inch and mm unit) to help you quickly find the sheet metal gauge thickness which including mild steel gauge thickness, aluminum gauge thickness, galvanized sheet gauge thickness, stainless steel gauge thickness.
You can also find the mm to gauge conversion for sheet metal by the chart provided below.
Therefore, there is no need to calculate by yourself according to the gauge to mm conversion formula.
