The Jiffy is the amount of time light takes to travel one femtometre (about the diameter of a nucleon). The Planck time is the time that light takes to travel one Planck length. The TU (for time unit) is a unit of time defined as 1024 μs for use in engineering. The svedberg is a time unit used for sedimentation rates (usually
In microeconomics, the marginal factor cost (MFC) is the increment to total costs paid for a factor of production resulting from a one-unit increase in the amount of the factor employed. [1] It is expressed in currency units per incremental unit of a factor of production (input), such as labor , per unit of time.
Peak demand on an electrical grid is the highest electrical power demand that has occurred over a specified time period (Gönen 2008). Peak demand is typically characterized as annual, daily or seasonal and has the unit of power. [ 1 ]
The rate of change of utility from changing the quantity of one good consumed is termed the marginal utility of that good. Marginal utility therefore measures the slope of the utility function with respect to the changes of one good. [9] Marginal utility usually decreases with consumption of the good, the idea of "diminishing marginal utility".
Nuclear power plants in France operate in load-following mode and so participate in the primary and secondary frequency control. Some units follow a variable load program with one or two large power changes per day. Some designs allow for rapid changes of power level around rated power, a capability that is usable for frequency regulation. [8]

The commission proposed making the standard hour the base unit of metric time, but the proposal did not gain acceptance and was eventually abandoned. [11] When the modern SI system was defined at the 10th General Conference on Weights and Measures (CGPM) in 1954, the ephemeris second (1/86400 of a mean solar day) was made one of the system's ...
