1. What is HP per Ton?

Definition: This calculator determines the horsepower per ton ratio, which measures power-to-weight ratio using 2000 lb (1 ton) as the reference.

Purpose: It helps evaluate vehicle and machinery performance by comparing power output to weight.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• HP/ton — Horsepower per ton ratio
• HP — Engine or motor horsepower
• W — Total weight in pounds

Explanation: The formula converts the weight to equivalent tons (by multiplying HP by 2000 lb/ton) and divides by actual weight to get the power-to-weight ratio.

3. Importance of HP per Ton Calculation

Details: This ratio is crucial for comparing vehicle performance, especially in automotive, aerospace, and heavy equipment industries.

4. Using the Calculator

Tips: Enter the horsepower and weight in pounds. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a good HP per ton ratio?
A: Passenger cars typically have 80-120 HP/ton, sports cars 150-250 HP/ton, and race cars 300+ HP/ton.

Q2: Why use 2000 in the formula?
A: 2000 lb equals 1 ton, converting the result to standard HP per ton units.

Q3: Can I use metric units?
A: This calculator uses imperial units. For metric (kW/tonne), use different conversion factors.

Q4: Does this include drivetrain loss?
A: No, this calculates theoretical ratio. For real-world performance, account for 10-15% power loss.

Q5: How does HP/ton affect acceleration?
A: Higher HP/ton generally means better acceleration, though gearing and traction also play roles.
