##### Lumens :

- The lumen is the unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time, in the International System of Units.
- Then, the symbol of lumens is
**lm**.

##### Candela :

- The candela is the unit of luminous intensity in the International System of Units.
- It measures luminous power per unit solid angle emitted by a light source in a particular direction.
- Then, the symbol of candela is
**cd**.

##### Lumens to Candela :

- Lumens refers to the total amount of light a lighting apparatus emits.
- We represent lumens as L.
- The higher the lumens value of a lighting device, the greater the area it illuminates.
- On the other hand, candela refers to the amount of light emitted by a lighting device in a particular direction.

##### Formula :

- The formula used to calculate the following calculator Lumens to Candela is given below.
- The apex angle in degrees value should be in assingment operator.
- So, the apex angle in degrees = Math.PI/180.
- Then the calculation formula = Enter Luminous flex in lumens / ( 2 * Math.PI * ( 1 – Math.cos ( The apex angle in degrees / 2 ))).
- Besides the formula this calculator works.

##### How to Calculate ?

- First, Enter the Luminous flex in lumens.
- Second, Enter the Apex angle in degrees.
- Click “Calculate” to get the result and then if you want to clear values Click “Reset” in addition to clear the values.
- Finally, follow these steps to get the results.
- Then you will get as a Luminous intensity result in candela.
