centi() → Units
Returns the derived Units having the 10^-2 (i.e., 0.01) prefix, centi (c).

compareTo(dynamic q2) → int
Compares this Quantity to q2 by comparing MKS values. The Quantities need not have the same dimensions.

Derive ElectricPotentialDifferenceUnits using this ElectricPotentialDifferenceUnits object as the base.
override

inherited
fromMks(dynamic mks) → Number
Calculates and returns the value in the units represented by this Units object of mks (that is expected to be in SI-MKS units). The method accepts a num or Number object; any other type will cause a QuantityException.
inherited
getShortestName(bool sing) → String
Returns the shortest name for the units. This will be the first non-null name found when inspecting secondary abbreviation, primary abbreviation and full name, in that order. If sing is true and no symbol or alternate name are available then the singular version of the name will be returned.
inherited
giga() → Units
Returns the derived Units having the 10^9 prefix, giga (G).
inherited
hecto() → Units
Returns the derived Units having the 10^2 (i.e., 100) prefix, hecto (h).
inherited
inverse() → Quantity
Determines the inverse of the quantity represented by this object, creating and returning a Quantity object (which may have different dimensions and therefore be of a different type). This object is not modified.
inherited
kilo() → Units
Returns the derived Units having the 10^3 (i.e., 1000) prefix, kilo (k).
inherited
mega() → Units
Returns the derived Units having the 10^6 prefix, mega (M).

inherited
outputText(StringBuffer buffer, {UncertaintyFormat uncertFormat = UncertaintyFormat.none, bool symbols = true, NumberFormat? numberFormat}) → void
Appends a String representation of this Quantity to the buffer using the preferred units and number format. If no preferred units have been specified, then MKS units are used. Uncertainty in the value of the Quantity is optionally shown as a plus/minus value in the same units.

Randomly generates a Quantity from this Quantity's value and uncertainty. The uncertainty is represented by a Normal (Gaussian) continuous distribution.
inherited

Returns the derived Units having the 10^12 prefix, tera (T).
inherited
toJson() → Map<String, dynamic>
Support dart:convert stringify.
inherited
toMks(dynamic value) → Number
Calculates and returns the value in SI-MKS units of the specified value (that is implicitly in these units). The method expects value to be a num or Number object; any other type will cause a QuantityException.
inherited
toString() → String
Returns a String representation of the Units in the following format:
inherited
valueInUnits(Units? units) → Number
Gets the Quantity's value in the specified units. If units is null, the MKS value is returned. If not null, units must have dimensions compatible with this Quantity or a DimensionsException will be thrown.

inherited
yotta() → Units
Returns the derived Units having the 10^24 prefix, yotta (Y).
inherited
zepto() → Units

inherited
zetta() → Units
Returns the derived Units having the 10^21 prefix, zetta (Z).
inherited

Operators

operator *(dynamic multiplier) → Quantity
Returns the product of this quantity and multiplier, which is expected to be either a Quantity, num or Number object. All other types will cause a QuantityException to be thrown.
