Weight Per Square Meter Formula:
| From: | To: |
Weight per square meter is a measurement of density that expresses how much weight is distributed over one square meter of area. It's commonly used in materials science, construction, and engineering to compare the density of different materials or structures.
The calculator uses the following formula:
Where:
Explanation: The formula converts the area from square millimeters to square meters by dividing by 1,000,000, then divides the weight by this converted area to get weight per square meter.
Details: This calculation is essential for determining material density, structural load capacity, and comparing material properties. It's particularly important in construction where weight distribution affects structural integrity.
Tips: Enter weight in kilograms and area in square millimeters. Both values must be positive numbers. The calculator will automatically convert the area to square meters and compute the weight per square meter.
Q1: Why convert from mm² to m²?
A: Square meters are the standard SI unit for area in most engineering and construction applications, while measurements are often taken in millimeters.
Q2: Can I use this for irregular shapes?
A: Yes, as long as you know the total area in mm² and total weight, the shape doesn't affect the calculation.
Q3: What's a typical weight per m² for building materials?
A: It varies widely - from about 2 kg/m² for thin plastic sheets to over 100 kg/m² for concrete slabs.
Q4: How accurate is this calculation?
A: It's mathematically precise, assuming accurate measurements of weight and area.
Q5: Can I calculate reverse - find weight from weight per m² and area?
A: Yes, simply multiply weight per m² by area in m² (or area in mm² divided by 1,000,000).
