Production Counter - Pieces per Time
Stopwatch with calculator for the porduction of a certain number of pieces per time. From the specified number of parts in a certain time, it is calculated how many parts will be produced in a different time if the production speed remains exactly the same. Enter, how many pieces in which time span are produced and stop or enter the duration. The number of pieces produced in this duration at a constant production rate will be calculated.
Example: a machine can produce 5 pieces in 8 minutes. Then it produces 75 pieces in two hours, if it runs constantly without a break.
Measuring with the stopwatch requires this page to remain open and the stopwatch to run throughout the measurement. This method is best suited for shorter time periods. The stopwatch measures to a tenth of a second, which becomes increasingly irrelevant as the duration increases. For measurements lasting several hours, you can simply look at a clock and enter the time difference.
This calculator can be used to determine a current production speed. Using values from the example above, this can be specified like 37.5 parts per hour. The extrapolated production value for a different duration will most likely not result in a whole number, but rather a decimal fraction. It will be rounded to two decimal places. Since produced parts are often whole pieces, which do not have, or should not have, fractions, this result should be understood as a theoretical average value. If the projected time span is used exactly, then the quantity of parts produced at a constant production rate is rounded down to this value. In this case, one piece is still in production, for example, within the machine.
Extrapolated production values in general involves several pitfalls, which are discussed in the calculator and article on extrapolation.
