Convert illuminance units (Lux ⇄ Foot-candles)
Result: -
Reference: 1 fc = 10.764 lux
Light affects every moment of our lives — our comfort, our mood, our health, and the quality of our work. Whether you're designing a home workspace, planning photography lighting, performing laboratory tests, or maintaining safe industrial environments — light measurement matters.
Illuminance tells us how much light lands on a surface, and the global standard unit used is Lux (lx). But different industries and countries use different measurement units:
Lux (lx) – Standard for lighting design
Foot-candles (fc) – Widely used in the U.S.
Lumens per square meter – Equivalent to lux
The Free Illuminance/Lux Converter by AlllinTools helps professionals and learners accurately convert lighting units for safety compliance, design optimization, and visual comfort — instantly.
Lighting should never be a guess.
Measure smarter → Illuminate better.
Lighting influences:
✔ Productivity & reading comfort
✔ Eye health and fatigue
✔ Building safety compliance
✔ Photography exposure quality
✔ Plant growth in horticulture
✔ Mood, retail atmosphere & design aesthetics
✔ Industrial and hazardous zone monitoring
Incorrect illumination can cause:
❌ Accidents and workplace injuries
❌ Headaches & vision strain
❌ Poor product display and lost sales
❌ Incorrect camera exposure
❌ Reduced plant growth & agriculture failures
Light carries real-world consequences — good and bad.
| Unit | Symbol | Used In |
|---|---|---|
| Lux | lx | Architecture, interior, photography, safety |
| Foot-candles | fc | U.S. construction, film & retail lighting |
| Phot | ph | Scientific lighting measurements |
| Nits (via conversion support) | cd/m² | Screen brightness evaluation |
✔ Automatically converts all units accurately
✔ Supports cross-discipline lighting work
Lux measures lumens distributed over a surface:
Lux = Lumens ÷ Area (m²)
Example:
1000 lumens spread across 10 m² → 100 lux
More light in a smaller area = higher lux level.
| Location / Task | Recommended Lux (lx) |
|---|---|
| Bedroom | 50–150 lx |
| Office desk work | 300–500 lx |
| Hospital operating room | 1000–2000 lx |
| Railway platforms | 200 lx |
| Supermarket aisles | 750 lx |
| Industrial inspection task | 1500 lx |
| Parking garage | 75 lx |
Standards come from organizations like:
📌 CIE (International Commission on Illumination)
📌 ISO & OSHA safety guidelines
Converting units supports legal compliance & worker safety.
🏢 Office & Workplace Lighting
Too little light causes fatigue
Too much glare creates discomfort
→ Balanced lux levels improve productivity
📸 Photography & Videography
Correct exposure requires precise light measurement
→ Perfect shots every time
🏡 Home Interiors
Mood lighting → Low lux
Reading or study room → Higher lux
🌿 Agriculture & Greenhouses
Light = food for plants
→ Incorrect lux → poor growth
🏭 Industrial Safety Standards
Conformance prevents accidents
→ Lighting audits require exact conversion
🏬 Retail & Display Lighting
More light → Higher product appeal
→ Measurable business impact
Light is a business accelerator.
📌 1 foot-candle = 10.764 lux
📌 1 lux ≈ 0.093 foot-candles
Example:
Retail lighting: 70 fc
→ 70 × 10.764 = 753.48 lx
AlllinTools calculates these instantly with clean precision.
| Brightness Level | Effect on Eyes |
|---|---|
| < 50 lx | Dim / insufficient |
| 100–500 lx | Comfortable working range |
| 1000+ lx | Strong brightness |
| 10,000 lx | Sunny outdoor daylight |
| >25,000 lx | Potential discomfort |
| >100,000 lx | Risk of eye damage |
Outdoor exposure needs sunglasses
Indoor exposure needs planning & design
Lighting affects:
