1. What is Miles per Watt?

Miles per watt-hour (mi/Wh) is a measure of how efficiently an electric vehicle converts electrical energy into distance traveled. It indicates how many miles the vehicle can travel using one watt-hour of energy.

2. How Does the Calculator Work?

The calculator uses a simple formula:

\[ \text{Efficiency} = \frac{\text{Miles Traveled}}{\text{Energy Consumed (Watt-hours)}} \]

Where:

Explanation: This ratio shows how effectively the vehicle converts electrical energy into motion. Higher values indicate better efficiency.

3. Importance of Efficiency Calculation

Details: Knowing your vehicle's miles per watt-hour helps estimate range, compare efficiency between vehicles, and calculate energy costs for trips.

4. Using the Calculator

Tips: Enter the total miles traveled and the total energy consumed in watt-hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a good miles per watt value for electric vehicles?
A: Typical values range from 0.1 to 0.4 mi/Wh. More efficient vehicles might achieve 0.5 mi/Wh or better.

Q2: How does this compare to MPGe?
A: MPGe (miles per gallon equivalent) is another efficiency metric that converts electricity to gasoline energy equivalents for comparison.

Q3: Can I use this for electric bikes/scooters?
A: Yes, the calculation works for any electric vehicle - cars, bikes, scooters, etc.

Q4: How can I improve my miles per watt?
A: Drive at steady speeds, reduce weight, maintain proper tire pressure, and use regenerative braking when available.

Q5: Should I use this for trip planning?
A: Yes, knowing your vehicle's efficiency helps estimate charging needs for long trips.
