The formula to calculate MSI is:
\[ \text{MSI} = \frac{L \times W}{1000} \]
Where:
MSI is short for mil-square inches and is a unit of measure equal to 1000 square inches. This term is most often used in the field of printing when looking at total print areas. Some other common terms used are MMSI, which is a unit of 1 million square inches, and MSF, which is a unit of 1000 square feet.
Let's consider an example:
Using the formula to calculate MSI:
\[ \text{MSI} = \frac{50 \times 20}{1000} = 1 \]
This means that with a length of 50 inches and a width of 20 inches, the MSI is 1.
