Description

The Lumen Calculator is a physics/math calculator designed to swiftly and easily convert between lumens, lux, and candelas.

Features:
- Instant calculation
- Results are copyable to other apps
- Formulas included as references
- Supports up to 16 decimal places
- Supports various units for each input

Definitions:
- Lumens: Unit of luminous flux, representing the total amount of light emitted by a source.
- Lux: Measure of surface illumination, indicating how much light is received by a surface.
- Candelas: SI units of luminous intensity, representing light emitted from a source in a particular direction per steradian.

Note:
Candelas measure the light emitted in a specific direction, while lux measures the light received per unit area. One steradian, the area of the receiving surface, is equal to the squared distance between the source and the receiver.

Formulas:
1. Lumens = Candelas * Ω
(For a specific angle)
2. Lumens = Candelas * 2π * [1 - cos(θ/2)]
3. Lux = Lumens / Area
4. Lux = Candela / Distance²

Where:
Ω = 2π * [1 - cos(θ/2)]
Ω = 4π

Not for me

This app does not do what I was led to believe it would produce. If this app is rated for age 4+, then I must be an idiot. Wish I could get my money back. Thank goodness it didn’t cost much!
