-
Supports luminance measurement units used in display and lighting fields
-
Browser-based and easy-to-use interface
-
Handles conversions relevant for cinema, automotive, and signage applications
Examples
-
10 candela/square foot equals 0.107639104 kilocandela/square meter
-
50 candela/square foot equals 0.53819552 kilocandela/square meter
Common Use Cases
-
Translating luminance values for display and monitor brightness specifications where imperial units are used
-
Calibrating projection screen brightness in cinema and theater environments
-
Assessing lighting design and signage brightness using square-foot area measurements
-
Specifying peak luminance for HDR displays and televisions
-

Tips & Best Practices
-
Ensure uniform brightness across measurement areas for accurate conversion results
-
Handle low luminance values carefully to minimize rounding inaccuracies
-
Use this conversion for consistent brightness communication across international standards
-
Apply the exact conversion factor: 1 candela/square foot = 0.0107639104 kilocandela/square meter
Limitations
-
Conversion assumes uniform luminance over the area and direct comparability between units
-
Surface characteristics and measurement direction may impact accuracy
-
Small kilocandela/square meter values require precise handling to avoid errors in low luminance
-
Results depend on conditions of measurement and may not account for all variables
