Displacement Tonnage Calculator for Ships

This calculator can be used to determine the displacement tonnage of a ship based on its volume and the density of seawater. Displacement tonnage is an important measure of a ship's size and weight, affecting its stability, buoyancy, and overall performance.

Input Parameters

Calculation Results

Calculation Formula

Displacement Tonnage (DT) = Ship Volume (V) × Seawater Density (ρ)

Where:
- Displacement Tonnage (DT) is the weight of the ship in tons (1 ton = 1000 kg)
- Ship Volume (V) is the total volume of the ship in cubic meters (m³)
- Seawater Density (ρ) is the density of seawater in kilograms per cubic meter (kg/m³)

How to Use the Calculator

  1. Enter the total volume of your ship in cubic meters (m³) in the "Ship Volume" field.
  2. The density of seawater is pre-filled at 1025 kg/m³, which is the average density of seawater at sea level. You can change this value if needed.
  3. Click the "Calculate" button to compute the displacement tonnage.
  4. The result will be displayed in the "Displacement Tonnage (tons)" field.
  5. If you want to start over, click the "Reset" button to clear all input fields.

Understanding Displacement Tonnage

Displacement tonnage is a measure of the total weight of a ship. It is calculated by multiplying the ship's volume by the density of the water it displaces. For ships, this is typically seawater with a density of approximately 1025 kg/m³.

The displacement tonnage is important for several reasons:

  • It affects the ship's buoyancy and stability.
  • It determines the ship's draft (how deep the ship sits in the water).
  • It is used in calculating the ship's cargo capacity and overall weight limits.

Example Calculation

If a ship has a volume of 5000 m³, the displacement tonnage would be:

Displacement Tonnage = 5000 m³ × 1025 kg/m³ = 5,125,000 kg = 5125 tons
