1 BTU/(h·ft²) = 3.1546 W/m²
Full precision:3.1546 W/m²
Step-by-Step Solution
To convert 1 btu/(h·ft²) to w/m², we multiply by 3.1546 because one btu per hour-square foot equals exactly 3.1546 w/m².
1 btu per hour-square foot = 3.1546 w/m²
Since each btu per hour-square foot contains 3.1546 w/m², we multiply our value by this factor:
1 × 3.1546 = 3.1546 w/m²
So 1 btu/(h·ft²) = 3.1546 w/m².
Quick check: 3.1546 ÷ 3.1546 = 1 btu/(h·ft²)
Example Conversions
Example 1: 1 BTU/(h·ft²) = 3.1546 W/m²
1 × 3.1546 = 3.1546
1 × 3.1546 = 3.1546
Example 2: 5 BTU/(h·ft²) = 15.7729 W/m²
5 × 3.1546 = 15.7729
5 × 3.1546 = 15.7729
Example 3: 10 BTU/(h·ft²) = 31.5459 W/m²
10 × 3.1546 = 31.5459
10 × 3.1546 = 31.5459
