Why industrial minutes exist
Payroll and time-tracking systems store work time as a decimal so it multiplies cleanly by an hourly rate. Sixty real minutes become 100 industrial minutes, which removes the base-60 arithmetic that makes normal minutes awkward to add up.
Quick reference
15 minutes is 25 industrial minutes, 30 minutes is 50, 45 minutes is 75, and a full hour is 100. To go the other way, multiply industrial minutes by 0.6 to get normal minutes.
Frequently asked questions
What is an industrial minute?
An industrial minute (Industrieminute) is one hundredth of an hour. Time is written as a decimal, so a full hour is 100 industrial minutes rather than 60. It makes work time easy to multiply by an hourly wage.
How do I convert minutes to industrial minutes?
Divide the minutes by 0.6, or multiply by 100 and divide by 60. For example, 45 minutes divided by 0.6 is 75 industrial minutes, and 30 minutes is 50.
How do I convert industrial minutes back to normal minutes?
Multiply by 0.6. For example, 75 industrial minutes times 0.6 is 45 normal minutes, and 50 is 30 minutes.
What are decimal hours (Industriestunden)?
Decimal hours apply the same idea to whole hours: 1 hour 30 minutes is 1.5 decimal hours, which is 150 industrial minutes. Decimal hours are simply the industrial minutes divided by 100.
