Volume to Weight Formula:
| From: | To: |
This calculator converts volume in cubic centimeters to weight in pounds using the material's density. It's useful for determining the weight of objects when you know their dimensions and material density.
The calculator uses the following formula:
Where:
Explanation: The formula first calculates volume in cubic centimeters, then converts it to weight using density, and finally converts grams to pounds.
Details: Density is crucial for accurate conversion since different materials with the same volume can have vastly different weights. For example, 1 cm³ of gold weighs much more than 1 cm³ of aluminum.
Tips: Enter the length measurement in centimeters and the material's density in g/cm³. Common densities: Water = 1 g/cm³, Aluminum = 2.7 g/cm³, Steel = 7.85 g/cm³, Gold = 19.32 g/cm³.
Q1: Why do I need density to convert volume to weight?
A: Weight depends on both volume and density. Different materials have different densities, so the same volume can result in different weights.
Q2: Where can I find density values for common materials?
A: Density tables are available online for metals, plastics, woods, and other common materials. Material specifications often include density.
Q3: Can I use this for irregular shapes?
A: This calculator assumes a perfect cube shape. For irregular shapes, you need to calculate the actual volume first.
Q4: How accurate is this conversion?
A: Accuracy depends on the precision of your measurements and the density value used. Temperature can also affect density for some materials.
Q5: What if my object isn't a perfect cube?
A: For other shapes, use the appropriate volume formula (e.g., for a sphere: V = (4/3)πr³) before applying the density conversion.
