1. What is Watts per Mile?

Watts per mile (W/mile) is a unit of measurement that quantifies the energy consumption rate of electric vehicles. It represents how many watts of power are used to travel one mile.

2. Conversion Formula

The calculator uses the simple conversion formula:

Where:

• 1 kWh = 1000 watts
• This converts the larger kilowatt-hour unit to the smaller watt unit

3. Government Standards

Details: Many government agencies and regulations use watts per mile as a standard metric for comparing vehicle efficiency and setting energy consumption standards.

4. Using the Calculator

Tips: Enter the energy consumption in kWh/mile (kilowatt-hours per mile). The default value of 3.5 kWh/mile is provided as a common reference point.

5. Frequently Asked Questions (FAQ)

Q1: Why convert kWh/mile to W/mile?
A: Watts per mile provides a more granular measurement that's often used in government regulations and technical specifications.

Q2: What's a good W/mile value?
A: Lower values are better. Typical EVs range from 200-400 W/mile (0.2-0.4 kWh/mile).

Q3: How does this relate to MPGe?
A: MPGe (Miles Per Gallon equivalent) is another metric that can be calculated from W/mile using additional conversion factors.

Q4: Why is 3.5 kWh/mile significant?
A: It's a common benchmark used in government energy efficiency calculations and comparisons.

Q5: Are there vehicle-specific variations?
A: Yes, actual consumption varies based on vehicle type, driving conditions, and other factors.
