Convert between lumens and lux (lx = lm/m²). Calculate foot-candles and understand ANSI lumens.
Calculating Lumen & Lux is a fundamental and crucial step in home theater design. It is not just about measuring distance; it must be designed based on scientific evidence to maximize human visual perception limits and immersion. Incorrect settings can cause eye strain or fail to take advantage of resolution benefits. This tool complies with industry standards such as THX and SMPTE guides to provide the most precise data.
This system utilizes complex trigonometry and optical formulas. Based on the input variables (screen size, resolution, viewing angle, etc.), it simultaneously calculates the minimum distance where pixels do not appear clustered and the maximum immersion distance that fills the entire field of view. All results are reflected in real-time, suggesting figures optimized for the user's environment.

Lux mengukur iluminansi per meter persegi. Lumen mengukur total keluaran cahaya. 1 lux = 1 lumen per meter persegi.
Lumen ANSI diukur di 9 titik pada layar. Peak lumen hanya di tengah dan 20–50 % lebih tinggi. Selalu bandingkan lumen ANSI.
