Preserve the same underlying stored value, but reset the stored unit identifier to the given unitType.
Preserve the same underlying stored value, but reset the stored unit identifier to the given unitType. Object attributes unitType, valueInSpecifiedUnits and valueAsString might be modified as a result of this method. For example, if the original value were "0.5cm" and the method was invoked to convert to millimeters, then the unitType would be changed to SVG_LENGTHTYPE_MM, valueInSpecifiedUnits would be changed to the numeric value 5 and valueAsString would be changed to "5mm".

Reset the value as a number with an associated unitType, thereby replacing the values for all of the attributes on the object.
Reset the value as a number with an associated unitType, thereby replacing the values for all of the attributes on the object. Exceptions: a DOMException with code NOT_SUPPORTED_ERR is raised if unitType is SVG_LENGTHTYPE_UNKNOWN or not a valid unit type constant (one of the other SVG_LENGTHTYPE_* constants defined on this interface). a DOMException with code NO_MODIFICATION_ALLOWED_ERR is raised when the length corresponds to a read only attribute or when the object itself is read only.

The type of the value as specified by one of the SVG_LENGTHTYPE_* constants defined on this interface.
The type of the value as specified by one of the SVG_LENGTHTYPE_* constants defined on this interface.

The value as a floating point value, in user units.
The value as a floating point value, in user units. Setting this attribute will cause valueInSpecifiedUnits and valueAsString to be updated automatically to reflect this setting. Exceptions on setting: a DOMException with code NO_MODIFICATION_ALLOWED_ERR is raised when the length corresponds to a read only attribute or when the object itself is read only.
MDN
The value as a string value, in the units expressed by unitType.
The value as a string value, in the units expressed by unitType. Setting this attribute will cause value, valueInSpecifiedUnits and unitType to be updated automatically to reflect this setting. Exceptions on setting: a DOMException with code SYNTAX_ERR is raised if the assigned string cannot be parsed as a valid <length>. a DOMException with code NO_MODIFICATION_ALLOWED_ERR is raised when the length corresponds to a read only attribute or when the object itself is read only.
