How to Use the Calculator
- Select the type of drum from the dropdown menu (Standard, 55-gallon, etc.).
- If using "Custom Dimensions", enter the height and diameter in centimeters.
- Select the material type (Steel, Plastic, Fiberglass).
- Enter the density of the liquid you will be storing (default is water at 1.0 kg/L).
- Click the "Calculate" button to compute the volume and weight capacity.
Understanding Drum Capacities
Drum capacities are typically measured in either liters or gallons. Standard drum sizes include:
- 55-gallon drum: Approximately 208 liters
- Standard drum: Approximately 200 liters
- Barrel: Approximately 44 gallons (about 166 liters)
- Jerry can: Typically 20 liters
Capacity Calculation Formula
The calculator uses the following formula to calculate drum volume:
Volume = π × r² × h
Where:
- π (pi) = 3.14159
- r = radius of the drum (diameter/2)
- h = height of the drum
Weight Capacity
The weight capacity is calculated by multiplying the volume by the liquid density. For example:
- Water (density 1.0 kg/L) in a 200-liter drum weighs 200 kg
- Soybean oil (density 0.92 kg/L) in a 200-liter drum weighs 184 kg
Practical Applications
This calculator can be used for:
- Estimating storage needs for chemicals, oils, or other liquids
- Planning shipping quantities
- Understanding material handling requirements
- Comparing different drum sizes for your specific needs
