Mortality rate, or death rate, is a measure of the number of deaths (in general, or due to a specific cause) in a particular population, scaled to the size of that population, per unit of time.
Basal metabolic rate
Basal metabolic rate (BMR) is the minimal rate of energy expenditure per unit time by endothermic animals at rest.
Birth rate
The birth rate (technically, births/population rate) is the total number of live births per 1,000 of a population in a year.
Frame rate
Frame rate, also known as frame frequency, is the frequency (rate) at which an imaging device displays consecutive images called frames.
Tempo
In musical terminology, tempo [ˈtɛmpo] ("time" in Italian; plural: tempi [ˈtɛmpi]) is the speed or pace of a given piece or subsection thereof, how fast or slow.
Radiant flux
In radiometry, radiant flux or radiant power is the radiant energy emitted, reflected, transmitted or received, per unit time, and spectral flux or spectral power is the radiant flux per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength.
Rotational speed
Rotational speed (or speed of revolution) of an object rotating around an axis is the number of turns of the object divided by time, specified as revolutions per minute (rpm), revolutions per second (rev/s), or radians per second (rad/s).
Clock rate
The clock rate typically refers to the frequency at which a chip like a central processing unit (CPU), one core of a multi-core processor, is running and is used as an indicator of the processor's speed.
Jerk (physics)
In physics, jerk, also known as jolt, surge, or lurch, is the rate of change of acceleration; that is, the derivative of acceleration with respect to time, and as such the second derivative of velocity, or the third derivative of position.
Mass flow rate
In physics and engineering, mass flow rate is the mass of a substance which passes per unit of time.
Throughput
In general terms, throughput is the maximum rate of production or the maximum rate at which something can be processed.
Heart rate
Heart rate is the speed of the heartbeat measured by the number of contractions of the heart per minute (bpm).
Frequency
Frequency is the number of occurrences of a repeating event per unit time.
Query throughput
In computer science, Query Throughput (QthD) is a measurement used to determine the performance of a database system.
Pulse repetition frequency
The pulse repetition frequency (PRF) is the number of pulses of a repeating signal in a specific time unit, normally measured in pulses per second.
Volumetric flow rate
In physics and engineering, in particular fluid dynamics and hydrometry, the volumetric flow rate, (also known as volume flow rate, rate of fluid flow or volume velocity) is the volume of fluid which passes per unit time; usually represented by the symbol Q (sometimes V̇).
