## How the conversion works

**Formula:**
```
MPGe = 3370.5 / kWh/100mi
```

**This can also be expressed as:**
```
MPGe = (33.705 kWh × 100) / kWh/100mi
```

**Where:**
- **MPGe** = Miles Per Gallon equivalent (the result)
- **kWh/100mi** = Energy consumption per 100 miles (your input)
- **33.705 kWh** = The EPA-defined energy content of one gallon of gasoline

**Why 33.705 kWh?**
The Environmental Protection Agency (EPA) established that one gallon of gasoline contains approximately 33.705 kilowatt-hours of energy (approximately 115,000 BTUs). This standardized conversion factor enables meaningful efficiency comparisons between electric and gasoline vehicles by expressing both in the same terms.

**Example Calculation:**
If an electric vehicle consumes 28 kWh per 100 miles:
- MPGe = 3370.5 / 28
- MPGe = 120.38
- The vehicle achieves 120.38 MPGe, indicating excellent efficiency

**Understanding the Relationship:**
Unlike the miles/kWh to MPGe conversion (which is a direct multiplication), the kWh/100mi to MPGe conversion is inverse. Lower kWh/100mi values mean higher efficiency (less energy to travel the same distance), resulting in higher MPGe ratings. This inverse relationship makes intuitive sense: using less energy means more equivalent miles per gallon.

## Efficiency rating scale

The tool provides an efficiency rating to help contextualize your conversion results:

**Excellent (100+ MPGe):**
Vehicles achieving over 100 MPGe represent outstanding efficiency. These typically include compact EVs, hyper-efficient sedans, and vehicles optimized for range and efficiency. Examples include the Tesla Model 3, Hyundai Ioniq 6, and Lucid Air. This corresponds to approximately 33.7 kWh/100mi or less.

**Good (80-100 MPGe):**
This range represents above-average EV efficiency. Most modern mid-size EVs and crossovers fall into this category, offering a solid balance between performance, size, and energy consumption. This corresponds to roughly 33.7-42 kWh/100mi.

**Average (60-80 MPGe):**
Typical efficiency for larger EVs, performance-focused models, or older electric vehicles. Some larger SUVs and trucks operate in this range, sacrificing some efficiency for utility or power. This corresponds to approximately 42-56 kWh/100mi.

**Below Average (<60 MPGe):**
Less efficient than typical EVs, often seen in large electric trucks, high-performance vehicles with aggressive driving, or EVs operating in challenging conditions. This corresponds to energy consumption above 56 kWh/100mi.

Note that even vehicles rated "Below Average" in EV terms typically still outperform gasoline vehicles in overall efficiency. The average new gasoline vehicle achieves approximately 25-30 MPG.

## Common EV consumption values

Here are typical kWh/100mi consumption rates for popular electric vehicles:

**Most Efficient EVs (Below 26 kWh/100mi):**
- Tesla Model 3 Long Range: ~25 kWh/100mi = 134.8 MPGe
- Hyundai Ioniq 6: ~24 kWh/100mi = 140.4 MPGe
- Lucid Air: ~26 kWh/100mi = 129.6 MPGe

**Efficient Crossovers/SUVs (26-32 kWh/100mi):**
- Tesla Model Y: ~27 kWh/100mi = 124.8 MPGe
- Chevy Bolt EV: ~28 kWh/100mi = 120.4 MPGe
- Kia EV6: ~29 kWh/100mi = 116.2 MPGe
- Nissan Leaf: ~30 kWh/100mi = 112.4 MPGe

**Larger EVs (32-45 kWh/100mi):**
- Ford Mustang Mach-E: ~33 kWh/100mi = 102.1 MPGe
- BMW iX: ~35 kWh/100mi = 96.3 MPGe
- Mercedes EQS SUV: ~38 kWh/100mi = 88.7 MPGe

**Electric Trucks (45+ kWh/100mi):**

- Ford F-150 Lightning: ~49 kWh/100mi = 68.8 MPGe
- GMC Hummer EV: ~55+ kWh/100mi = 61.3 MPGe

These values represent EPA combined city/highway ratings. Actual consumption varies based on driving conditions.

## FAQs

**
**Q:** Why does my EV's kWh/100mi vary from the EPA rating?**


**A:** Real-world consumption depends on numerous factors: driving speed, acceleration habits, terrain, climate control usage, and outside temperature. Highway driving at high speeds typically increases consumption, while city driving with regenerative braking may improve it. Cold weather significantly increases consumption due to battery heating and cabin heating demands.

**
**Q:** How do I find my EV's current kWh/100mi consumption?**


**A:** Most EVs display this on the dashboard or infotainment system, either as a trip average or real-time reading. You can also calculate it manually by dividing the kWh charged by the miles driven between charges. Many EV apps and charging networks also track this metric over time.

**
**Q:** Is lower kWh/100mi always better?**


**A:** From a pure efficiency standpoint, yes—lower consumption means more range from the same battery capacity and lower operating costs. However, higher consumption might come with benefits like more power, larger vehicle size, or all-wheel drive. The best vehicle balances efficiency with your specific needs.

**
**Q:** How does temperature affect my EV's consumption?**


**A:** Temperature significantly impacts EV efficiency. Cold weather (below 40°F/4°C) can increase consumption by 20-40% due to battery heating requirements and reduced regenerative braking efficiency. Very hot weather increases consumption moderately due to air conditioning demands. Temperate conditions (65-75°F/18-24°C) typically yield the best efficiency.

**
**Q:** Why is MPGe useful instead of just using kWh/100mi?**


**A:** MPGe provides a familiar reference point for consumers transitioning from gasoline vehicles. When someone sees 120 MPGe, they can immediately understand this is much more efficient than a typical 30 MPG gasoline car—a comparison that's less intuitive with kWh/100mi alone.

**
**Q:** Can I compare MPGe directly to gasoline MPG?**


**A:** Yes, that's the primary purpose of MPGe. If your EV achieves 120 MPGe, it uses the same amount of energy to travel 120 miles as a gasoline car would burning one gallon of gas. This makes cost and efficiency comparisons straightforward, though note that electricity prices vary more than gasoline prices by location.

**
**Q:** What's a typical charging cost based on kWh/100mi?**


**A:** To estimate cost, multiply your kWh/100mi by your electricity rate. For example, at $0.15/kWh, a vehicle consuming 30 kWh/100mi costs $4.50 per 100 miles. Compare this to a 30 MPG gasoline car at $3.50/gallon, which costs $11.67 per 100 miles—showing the typical EV operating cost advantage.
