In daily work, Hangzhou Qizhang Automation Technology Co., Ltd. often encounters the customer's requirement that the edge pressure of the packaging carton material should reach a certain value, because the level of the edge pressure strength directly affects the empty box compressive strength of the carton.
Some common foreign customers use the unit provided by the foreign party as the English unit and the unit commonly used in China is the metric unit, as follows:
Imperial units: Lb/in Lb/4in (lbs and inches) Metric units: N/100mm N/m kN/m (Newton and meters)
The units of English and metric are converted as follows:
1Lb/in=17.5N/100mm
1Lb/in=175N/m
1Lb/in==0.175kN/m
Conversely, if the metric is converted to English, the conversion is as follows:
1k.N/m=1000N/m
1N/m=0.0057Lb/in
1N/100mm=0.057Lb/in
In general, it can be classified as such a coefficient law, namely:
If converted to metric in English, the coefficient is: 175. If the metric system is converted to English, the coefficient is 0.057. Of course, in the actual operation, we should also pay attention to the order of magnitude of the coefficient.
