PowerUnit enum

Represents units of power.

This enum implements the LinearUnit interface to provide conversion capabilities and a display symbol for each power unit. All conversion factors are pre-calculated in the constructor relative to the Watt (W).

Values

watt → const PowerUnit: Watt (W), the SI derived unit of power, equal to one Joule per second.

const PowerUnit(1, 'W')
nanowatt → const PowerUnit: Nanowatt (nW), used in semiconductor sleep-state power profiling.

const PowerUnit(PowerFactors.wattsPerNanowatt, 'nW')
microwatt → const PowerUnit: Microwatt (µW), critical for IoT devices and RFID.

const PowerUnit(PowerFactors.wattsPerMicrowatt, 'µW')
milliwatt → const PowerUnit: Milliwatt (mW), a sub-multiple of the Watt, common in electronics.

const PowerUnit(PowerFactors.wattsPerMilliwatt, 'mW')
kilowatt → const PowerUnit: Kilowatt (kW), a common multiple of the Watt.

const PowerUnit(PowerFactors.wattsPerKilowatt, 'kW')
megawatt → const PowerUnit: Megawatt (MW), a common multiple of the Watt, used for large-scale power.

const PowerUnit(PowerFactors.wattsPerMegawatt, 'MW')
gigawatt → const PowerUnit: Gigawatt (GW), a multiple of the Watt, used for large power plants.

const PowerUnit(PowerFactors.wattsPerGigawatt, 'GW')
terawatt → const PowerUnit: Terawatt (TW), standard scale for global energy consumption.

const PowerUnit(PowerFactors.wattsPerTerawatt, 'TW')
horsepower → const PowerUnit: Mechanical Horsepower (hp), a common unit for engine and motor power.

const PowerUnit(PowerFactors.wattsPerHorsepower, 'hp')
metricHorsepower → const PowerUnit: Metric Horsepower (PS), used commonly in the automotive industry.

const PowerUnit(PowerFactors.wattsPerMetricHorsepower, 'PS')
btuPerHour → const PowerUnit: British Thermal Unit per hour (Btu/h), common in HVAC.

const PowerUnit(PowerFactors.wattsPerBtuPerHour, 'Btu/h')
ergPerSecond → const PowerUnit: Erg per second (erg/s), the power unit in the CGS system.

const PowerUnit(PowerFactors.wattsPerErgPerSecond, 'erg/s')

Properties

hashCode → int: The hash code for this object.
no setterinherited
index → int: A numeric identifier for the enumerated value.
no setterinherited
isMetric → bool: Returns false for the imperial horsepower and btuPerHour, the CGS ergPerSecond, and metricHorsepower ("metric" in name only — defined via kgf·m/s, not an SI unit); true for all decimal multiples/submultiples of the watt.
no setteroverride
isSI → bool: Returns true only for watt, the SI derived unit of power.
no setteroverride
name → String: Available on Enum, provided by the EnumName extension
The name of the enum value.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
symbol → String: The human-readable symbol for this power unit (e.g., "W", "kW", "hp").
