    A man-hour or human-hour is the amount of work performed by the average worker in one hour. [1] [2] It is used for estimation of the total amount of uninterrupted labor required to perform a task.

  3. Utilization rate - Wikipedia

    en.wikipedia.org/wiki/Utilization_rate

    Looked at simply, there are two methods to calculate the utilization rate. The first method calculates the number of billable hours divided by the number of hours recorded in a particular time period. For example, if 40 hours of time is recorded in a week but only 30 hours of that was billable, the utilization rate would then be 30 / 40 = 75%.

  4. K factor (traffic engineering) - Wikipedia

    en.wikipedia.org/wiki/K_factor_(traffic_engineering)

    In transportation engineering, the K factor is defined as the proportion of annual average daily traffic occurring in an hour. [1] This factor is used for designing and analyzing the flow of traffic on highways. K factors must be calculated at a continuous count station, usually an "automatic traffic recorder", for a year before being determined.

  5. Failure rate - Wikipedia

    en.wikipedia.org/wiki/Failure_rate

    The Failures In Time (FIT) rate of a device is the number of failures that can be expected in one billion (10 9) device-hours of operation [17] (e.g. 1,000 devices for 1,000,000 hours, or 1,000,000 devices for 1,000 hours each, or some other combination).

    [citation needed] Japan has enacted an 8-hour work day and 40-hour work week (44 hours in specified workplaces). The overtime limits are: 15 hours a week, 27 hours over two weeks, 43 hours over four weeks, 45 hours a month, 81 hours over two months and 120 hours over three months; however, some workers get around these restrictions by working ...

  7. Heating degree day - Wikipedia

    en.wikipedia.org/wiki/Heating_degree_day

    As total energy consumption is in kilowatt hours and heating degree days are [no. days×degrees] we must convert watts per kelvin into kilowatt hours per degree per day by dividing by 1000 (to convert watts to kilowatts), and multiplying by 24 hours in a day (1 kW = 1 kW⋅h/h).

  8. Sunshine duration - Wikipedia

    en.wikipedia.org/wiki/Sunshine_duration

    Sunshine duration or sunshine hours is a climatological indicator, measuring duration of sunshine in given period (usually, a day or a year) for a given location on Earth, typically expressed as an averaged value over several years.

  9. Full-time equivalent - Wikipedia

    en.wikipedia.org/wiki/Full-time_equivalent

    For example, a full week of 40 hours has an FTE value of 1.0, so a person working 20 hours would have an FTE value of 0.5. Certain industries may adopt 35 hours, depending on the company, its location and the nature of work. Whole-time equivalent (WTE) is the same as FTE and applies also to students in education. [7]
