CFT to MT Formula:
| From: | To: |
The CFT to Metric Tonnes conversion calculates the weight of a material in metric tonnes based on its volume in cubic feet and its density. This conversion is essential in industries like shipping, construction, and logistics where materials are measured by volume but priced by weight.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts volume measurement (cubic feet) to weight measurement (metric tonnes) using the material's density as the conversion factor.
Details: Accurate density values are crucial for precise conversions. Different materials have different densities - for example, water has a density of 62.4 lb/ft³, while sand can range from 90-110 lb/ft³ depending on moisture content and composition.
Tips: Enter the volume in cubic feet and the material density in pounds per cubic foot. Both values must be positive numbers. Common density values can be found in material specification sheets or engineering handbooks.
Q1: Why is the conversion factor 35.315?
A: This factor comes from the relationship between pounds and metric tonnes (1 metric tonne = 2204.62 pounds) and the definition of cubic foot measurement.
Q2: Can I use this calculator for any material?
A: Yes, as long as you know the material's density in pounds per cubic foot. The calculator works for solids, liquids, and granular materials.
Q3: How accurate is this conversion?
A: The accuracy depends entirely on the accuracy of the density value used. For precise calculations, use measured density values rather than estimated ones.
Q4: What's the difference between metric tonnes and regular tons?
A: A metric tonne (1000 kg) is slightly heavier than a US short ton (2000 lb or ~907 kg) but lighter than a UK long ton (2240 lb or ~1016 kg).
Q5: When would I need this conversion?
A: This conversion is commonly used in international shipping, bulk material purchasing, construction projects, and any industry that needs to convert between volumetric and weight measurements.
