Industrial time

Industrial time

The Industrial Age brought with it the invention of the factory system and with it a new way of calculating time. Industrial time is calculated in minutes and seconds, not hours and minutes. The advantage of this system is that it allows more accurate measurements when timing work processes.

Industry time calculates how much work was done in a given period of time. It can also be used to calculate wage rates for workers. Converting between Standard Time and Industrial Time can be tricky, but with practice, it becomes second nature.

Anyone working in time attendance management needs to know about industry minutes and times. In contrast to "ordinary minutes", a working hour does not correspond to 60 minutes, but to 100 decimal minutes in business life.

This article explains the difference between industrial time and standard time, calculates it, and converts between them. You'll end up being an industrial time expert!

What is industrial time?

The term "industrial time" refers to the way time is calculated and measured in an industrial setting. In an industrial setting, time is measured in minutes and seconds, not hours and minutes.

In industrial time, an hour is represented as 1 and a half hours as 1.5. The display is mainly used in operational working time documentation and is intended to support data management.

This system has the advantage that it measures more precisely how long work processes take. For example, if an employee is paid by the hour, their wages are based on the number of hours worked. However, their pay is more accurate if their pay is based on the number of minutes they worked.

Why is it calculated in industrial minutes?

Working time calculations are much easier than in real-time. For this reason, industrial time is important for recording working hours in many companies. The format documents the employees' daily working hours and their break times. 

This system is less confusing and more accurate than other methods, such as B. Using a clock or stopwatch. Businesses using this format can ensure that they accurately represent their employees' working hours.

What are the advantages of the industrial age?

The Industrial Age was a time of great change for mankind. It was a time when new technologies and ideas changed the way we live, work, and think. One of the most important changes has been the way we use and measure time.

The industrial age brought with it a new understanding of time and its meaning. People used to measure time according to the sun and the seasons. But with the advent of the industrial age, people began to understand that time could be measured more accurately and precisely.

Most German companies use industry logs to record the working hours of their employees. The time data is easier to add and manage, which is why this is the preferred option. For things like payroll, all you have to do is add up the numerical values ​​and don't have to worry about decimal places or real minutes. Therefore, all modern time recording systems work with industrial time.

The Industrial Age value is best demonstrated with an example:

  • Real time: 2 hours 32 minutes
  • Real time: 1 hour 48 minutes
  • Real time: 3 hours 39 minutes

You must first add up the perfect minutes to calculate the total hours worked using the real times provided. In this scenario, the end result would be a number greater than 60, so the second stage requires switching from traditional minutes to hours.

Summing up the minutes above gives 119 actual minutes, equal to 1 hour and 59 minutes. You then calculate the actual hours and come up with six hours. This results in a total value of seven real hours and 59 real minutes. To illustrate, this conversion is much more tedious than other methods.

Industrial time minutes are mainly used in time recording systems, payroll accounting, and working time calculation. It's much easier to do calculations. In addition to regular minutes, the working hours can be displayed with industry minutes in decimal form. The decimal places of the working time (working minutes) are not lost - they are extrapolated to 100. 

Industrial Minutes with example values:

Real Minutes = Decimal Hours / Industrial

  • Hours 30 seconds = 0.01

  • 1 minute = 0.02

  • 2 minutes = 0.03

  • 5 minutes = 0.08

  • 10 minutes = 0.17

  • 15 minutes = 0.25

  • 20 minutes = 0 .33

  • 45 minutes = 0.75

  • 60 minutes = 1

Minutes and seconds: conversion at a glance

The typical times, for example, 3 hours and 45 minutes, cannot simply be added up. In the decimal form of working time, this time would be changed to 3.75 hours. The idea behind this calculation is:

  • An hour has 60 minutes.
  • To convert minutes to hours, divide by 60 (3 hours = 3 x 60 minutes = 180 minutes).
  • 45 minutes equals 0.75 hours (45/60 = 0.75).
  • So 3 hours and 45 minutes equal 3.75 hours.

You can use this approach to quickly convert minutes to their decimal hours equivalent.

How do you calculate industrial time?

Once you know the basics of arithmetic, figuring out industrial time is easy. You take the number of minutes and divide it by 60. This gives you the number of hours in decimal form.

Industrial time = real hours + real minutes/60

Suppose you want to calculate industrial time for 2 hours and 30 minutes.

You would take 2 hours and divide by 60 which would give you 0.03 hours. Then you would take 30 minutes and divide by 60 which gives you 0.5 hours. Adding these two together gives you 0.53 hours of industrial time.

When normal seconds are included, the calculation becomes more difficult. The formula for this is:

industrial time = real hours + real minutes/60 + real seconds/3600 Convert

Industrial time to standard time: How do you convert industrial minutes?

Switching from industrial to real-time is a bit more complicated. Note the following correspondences:

  • 0.25 = 15 minutes

  • 0.5 = 30 minutes

  • 0.75 = 45 minutes

For example, 4.75 real-time industrial hours is four hours and 45 minutes.

With an industry time of 5.38, you can take a different approach. The hours are transferred unchanged to real-time, i.e. initially ignored. However, to undo the previous calculation method, the industry minutes are multiplied by 60.

  • Actual Minutes = Industry Minutes x 60

  • Actual Minutes = 0.38 x 60 = 22.8 (about 23 Actual Minutes)

The actual minutes and hours are then added together. In this case, that's five hours and 23 minutes. In such cases, it is essential to round up or down.

How do you calculate decimal minutes?

Modern-time recording systems are used in a variety of industries. The difference between labor time and human effort is usually expressed in decimal format instead of the more common hour-based method. For example 8.75 industry hours instead of 8 hours and 45 minutes. Sometimes the term industrial minute is also used for decimal minutes.


Industrial time is a system that is mainly used for time recording and billing of wages and working hours. There are advantages to using this method, e.g. B. the ease of calculation and the ability to record decimal minutes. To convert from industrial to real-time or vice versa, a few simple steps need to be followed. Calculating industrial time will soon become second nature with practice.
