+page-type: web-api-instance-method
+browser-compat: api.SVGAngle.convertToSpecifiedUnits
+---
+
+{{APIRef("SVG")}}
+
+The `convertToSpecifiedUnits()` method of the {{domxref("SVGAngle")}} interface allows you to convert the angle's value to the specified unit type.
+
+This function will:
+
+- Set the {{domxref("SVGAngle.unitType", "unitType")}} property to the given unit type
+- Update the {{domxref("SVGAngle.valueInSpecifiedUnits", "valueInSpecifiedUnits")}} and {{domxref("SVGAngle.valueAsString", "valueAsString")}} properties so the angle value is represented in the given unit type
+
+## Syntax
+
+```js-nolint
+svgAngle.convertToSpecifiedUnits(unitType)
+```
+
+### Parameters
+
+- `unitType`
+  - : A constant representing the unit type to which the angle's value should be converted. This must be one of the constant values defined for the {{domxref("SVGAngle.unitType", "unitType")}} property, with the exception of `SVG_ANGLETYPE_UNKNOWN`.
+    - `SVGAngle.SVG_ANGLETYPE_DEG`: convert to degrees
+    - `SVGAngle.SVG_ANGLETYPE_RAD`: convert to radians
+    - `SVGAngle.SVG_ANGLETYPE_GRAD`: convert to gradians
+    - `SVGAngle.SVG_ANGLETYPE_UNSPECIFIED`: convert to a unitless number, interpreted as degrees
+
+### Return value
+
+None ({{jsxref('undefined')}}).
+
+## Examples
+
+### Converting an angle to degrees
+
+```js
+// Get an SVGAngle object
+const svg = document.querySelector("svg");
+const angle = svg.createSVGAngle();
+
+// Set the angle's value in radians (Math.PI / 2)
+angle.newValueSpecifiedUnits(SVGAngle.SVG_ANGLETYPE_RAD, Math.PI / 2);
+
+// Retrieve the angle's value as a string
+console.log(angle.valueAsString); // Output: 1.5708rad
+console.log(angle.unitType); // Output: 3 (SVG_ANGLETYPE_RAD)
+
+// Convert the angle's value to degrees
+angle.convertToSpecifiedUnits(SVGAngle.SVG_ANGLETYPE_DEG);
+
+// Retrieve the angle's value as a string
+console.log(angle.valueAsString); // Output: 90deg
+console.log(angle.unitType); // Output: 2 (SVG_ANGLETYPE_DEG)

+The `newValueSpecifiedUnits()` method of the {{domxref("SVGAngle")}} interface resets the value as a number with an associated {{domxref("SVGAngle.unitType", "unitType")}}, thereby replacing the values for all of the attributes on the object.
+
+## Syntax
+
+```js-nolint
+svgAngle.newValueSpecifiedUnits(unitType, valueInSpecifiedUnits)
+```
+
+### Parameters
+
+- `unitType`
+
+  - : A constant representing the unit type to which the angle's value should be converted. This must be one of the constant values defined for the {{domxref("SVGAngle.unitType", "unitType")}} property, with the exception of `SVG_ANGLETYPE_UNKNOWN`.

+
+- `valueInSpecifiedUnits`
+  - : The numeric factor for the angle value, expressed in the specified unit type.
+
+### Return value
+
+None ({{jsxref('undefined')}}).
+
+### Exceptions
+
+This method may raise a {{domxref("DOMException")}} of one of the following types:
+
+- `NotSupportedError` {{domxref("DOMException")}}
+
+  - : Thrown if `unitType` is `SVG_ANGLETYPE_UNKNOWN` or not a valid unit type constant.
+
+- `NoModificationAllowedError` {{domxref("DOMException")}}
+  - : Thrown if {{domxref("SVGAngle")}} corresponds to a read-only attribute or when the object itself is read-only.

+## Examples

+### Setting an angle in degrees
+
+```js
+// Get an SVGAngle object
+const svg = document.querySelector("svg");

+
+// Set the angle's value in degrees using newValueSpecifiedUnits()
+angle.newValueSpecifiedUnits(SVGAngle.SVG_ANGLETYPE_DEG, 45);
+
+// Retrieve the angle's value in degrees
+console.log(angle.value); // Output: 45
+console.log(angle.unitType); // Output: 2 (SVG_ANGLETYPE_DEG)

+const angle = svg.createSVGAngle();
+
+// Set the angle's value in radians using newValueSpecifiedUnits()
+angle.newValueSpecifiedUnits(SVGAngle.SVG_ANGLETYPE_RAD, Math.PI / 2);
+
+// Retrieve the angle's value
+console.log(angle.value); // Output: 90

+
+// Set the angle's value in gradians using newValueSpecifiedUnits()

+
+The **`unitType`** property of the {{domxref("SVGAngle")}} interface is one of the [unit type contants](/en-US/docs/Web/API/SVGAngle#constants) and represents the units in which this angle's value is expressed. 
+
+## Value
+
+An `integer`; the angle type as an unsigned short.
+
+## Examples
+
+Here's an example of how to access the `unitType` property:
+
+```js
+// Get an SVGAngle object
+const svg = document.querySelector("svg");
+
+// Assume `angle` is an instance of SVGAngle
+const angle = svg.createSVGAngle();
+
+// Set the angle value
+angle.newValueSpecifiedUnits(SVGAngle.SVG_ANGLETYPE_DEG, 45);
+
+// Check the unit type
+console.log(angle.unitType); // Output: 2 (SVG_ANGLETYPE_DEG)
