This calculator will help you calculate how many thousand square inches (MSI) or thousand square feet (MSF) there are in a roll. One application where this might be useful is knowing how much material will run through a press. As always, use this as an estimation, but please contact sales for more precise information.
Example
Let’s calculate the MSI and MSF for a roll of 45 lb Ivex crepe paper that has a roll weight of 1166 lbs.
Formula – MSI:
NOTE: MSI should be rounded to the nearest whole number.
Formula – MSF:
NOTE: MSF should be rounded to three decimal places.
