Conversion Formula:
From: | To: |
This conversion transforms power density measurements from metric (watts per square meter) to imperial (watts per square foot) units. It's commonly used in lighting design, solar panel installations, and building energy calculations.
The calculator uses the conversion formula:
Where:
Explanation: This linear conversion accounts for the area difference between metric and imperial units.
Details: Accurate unit conversion is essential when working with international standards, comparing specifications, or applying calculations in regions using different measurement systems.
Tips: Enter watts per square meter value (must be positive). The calculator will automatically compute the equivalent in watts per square foot.
Q1: Why is 10.764 the conversion factor?
A: Because 1 square meter equals exactly 10.76391041671 square feet (rounded to 10.764 for practical calculations).
Q2: When would I need this conversion?
A: Common applications include lighting design (lux to foot-candles), solar panel output, and building energy efficiency calculations.
Q3: Is the conversion linear?
A: Yes, the relationship is linear as it's purely a unit area conversion, not involving any power changes.
Q4: Can I convert back from W/sq ft to W/m²?
A: Yes, simply multiply W/sq ft by 10.764 to get W/m².
Q5: How precise should these calculations be?
A: For most practical purposes, 4 decimal places are sufficient, though the calculator can handle more precise values.
