Capacity or capacities may refer to:
Mathematics, science, and engineering
* Capacity of a container, closely related to
the volume of the container
*
Capacity of a set
In mathematics, the capacity of a set in Euclidean space is a measure of the "size" of that set. Unlike, say, Lebesgue measure, which measures a set's volume or physical extent, capacity is a mathematical analogue of a set's ability to hold electr ...
, in Euclidean space, the total charge a set can hold while maintaining a given potential energy
*
Capacity factor
The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. The theoretical maximum energy output of a given installation is def ...
, the ratio of the actual output of a power plant to its theoretical potential output
*
Storage capacity (energy), the amount of energy that the storage system of a power plant can hold
*
Nameplate capacity
Nameplate capacity, also known as the rated capacity, nominal capacity, installed capacity, maximum effect or gross capacity,Heat capacity
Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to an object to produce a unit change in its temperature. The SI unit of heat capacity is joule per kelvin (J/K).
Heat capacity is a ...
, a measurement of changes in a system's internal energy
*
Combining capacity, another term for valence in chemistry
*
Battery capacity, the amount of electric charge a battery can deliver at the rated voltage
Computer
*
Data storage capacity, amount of stored information that a storage device or medium can hold
*
Channel capacity
Channel capacity, in electrical engineering, computer science, and information theory, is the theoretical maximum rate at which information can be reliably transmitted over a communication channel.
Following the terms of the noisy-channel coding ...
, the highest rate at which information can be reliably transmitted

Carrying capacity
The carrying capacity of an ecosystem is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available. The carrying capacity is defined as the ...
, the population size of a species that its environment can sustain
*
Capacity planning
Capacity planning is the process of determining the production capacity needed by an organization to meet changing demands for its products. In the context of capacity planning, design capacity is the maximum amount of work that an organization o ...
, the process of determining the production resources needed to meet product demand
*
Capacity building
Capacity building (or capacity development, capacity strengthening) is the improvement in an individual's or organization's facility (or capability) "to produce, perform or deploy". The terms capacity building and capacity development have often ...
, strengthening the skills, competencies and abilities of developing societies
*
Productive capacity
Productive capacity is the maximum possible output (economics), output of an economy. According to the United Nations Conference on Trade and Development (UNCTAD), no agreed-upon definition of maximum output exists. UNCTAD itself proposes: "the pr ...
, the maximum possible output of an economy
*
Capacity management
Capacity management's goal is to ensure that information technology resources are sufficient to meet upcoming business requirements cost-effectively. One common interpretation of capacity management is described in the ITIL framework. ITIL vers ...
, a process used to manage information technology in business
*
Capacity utilization
Capacity utilization or capacity utilisation is the extent to which a firm or nation employs its installed productive capacity (maximum output of a firm or nation). It is the relationship between output that ''is'' produced with the installed ...
, the extent to which an enterprise or a nation uses its theoretical productive capacity
* Road capacity, the maximum
traffic flow
In transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the ai ...
