What Is This Tool?

This converter transforms illumination measurements from nox, a unit representing very low light levels typical of night-time or near-dark environments, into foot-candles, a widely used unit in lighting practices across North America for specifying luminous flux per square foot.

How to Use This Tool?

  • Enter the illumination value in nox you want to convert
  • Select nox as the starting unit and foot-candle as the target unit
  • Click convert to see the equivalent foot-candle value instantly

Key Features

  • Converts illumination values from nox to foot-candles quickly and easily
  • Supports units relevant to low-light and architectural, environmental, or stage lighting contexts
  • Provides clear conversion with a precise rate for practical application
  • Helps bridge specialized astronomical or environmental illuminance with common lighting standards

Examples

  • 10 Nox converts to 0.00092903 Foot-candle
  • 100 Nox converts to 0.0092903 Foot-candle

Common Use Cases

  • Describing natural night lighting conditions like moonlight or starlight in astronomy
  • Designing outdoor lighting with very low background illumination for dark-sky compliance
  • Setting illumination standards for offices, retail spaces, and horticultural lighting
  • Adjusting light exposure in photography, film, and stage environments

Tips & Best Practices

  • Use this tool when working with very low illuminance requiring conversion to common North American lighting units
  • Apply conversions to help meet building codes and lighting design criteria
  • Be aware this converter links a historical unit to a practical lighting measurement used in many industries

Limitations

  • Nox is designed for extremely low light levels and might not suit higher illumination ranges where foot-candle is preferred
  • Since foot-candle is a non-SI unit, some rounding variations could occur when used in strictly scientific SI contexts

Frequently Asked Questions

What does one nox represent?
One nox is a unit of illuminance for very low light, equal to one millilux or 0.001 lux.

Why convert nox to foot-candle?
Converting nox to foot-candle helps express very low light levels using a unit common in North American lighting practices for easier interpretation and compliance.

Is foot-candle an SI unit?
No, foot-candle is a non-SI unit measuring luminous flux per square foot commonly used in certain lighting industries.

Key Terminology

Nox
A specialized illuminance unit representing very low light levels, equal to one millilux (0.001 lux), used in night-time and near-dark conditions.
Foot-candle [ft*c, fc]
A non-SI unit of illuminance equal to one lumen per square foot, commonly applied in North American lighting for measuring luminous flux incident on surfaces.
