Conversion Formula:
| From: | To: |
The square feet to kilograms conversion calculates the weight of a material based on its area, thickness, and density. This is particularly useful in construction, manufacturing, and material estimation where you need to determine the weight of sheet materials.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts square feet to square meters, then multiplies by thickness to get volume, and finally multiplies by density to calculate weight.
Details: Accurate weight calculation is crucial for structural planning, shipping costs estimation, material procurement, and load-bearing calculations in construction and manufacturing.
Tips: Enter area in square feet, thickness in meters, and density in kg/m³. All values must be positive numbers. Common material densities: steel (7850 kg/m³), aluminum (2700 kg/m³), wood (500-800 kg/m³).
Q1: Why is there a conversion factor of 10.764?
A: This factor converts square feet to square meters (1 ft² = 0.092903 m², so 1/0.092903 ≈ 10.764).
Q2: Can I use different units for thickness?
A: The calculator requires thickness in meters. Convert from other units first (1 inch = 0.0254 meters, 1 mm = 0.001 meters).
Q3: Where can I find material density values?
A: Material density values are available in engineering handbooks, material specification sheets, or online material databases.
Q4: Is this calculation accurate for all materials?
A: The calculation assumes uniform density throughout the material. It may not be accurate for materials with varying density or composite materials.
Q5: Can this calculator be used for liquids?
A: While the principle is similar, liquid calculations typically use volume units (gallons/liters) rather than area and thickness.
