## How it works

The converter applies a two-step process. First, it converts kWh/100km to kilometers per kWh by dividing 100 by the consumption value (km/kWh = 100 ÷ kWh/100km). This step inverts the consumption metric into an efficiency metric. Second, it converts kilometers per kWh to miles per kWh by dividing by the conversion factor 1.60934 (since 1 mile equals 1.60934 kilometers). The combined formula simplifies to: miles/kWh = 62.137 ÷ kWh/100km. This calculation accounts for both the dimensional inversion (from consumption to efficiency) and the unit conversion between metric and imperial systems.

## Who should use this

EV owners shopping for cars who need to compare vehicle efficiency ratings across different markets, automotive journalists writing about electric vehicles sold internationally, car dealerships with inventory from both European and North American manufacturers, environmental researchers tracking EV efficiency trends across regions, and fleet managers evaluating electric vehicles for purchase decisions in markets using different efficiency standards.

## Worked examples

Example 1: A European EV specification shows 15 kWh/100km consumption. Using the formula: miles/kWh = 62.137 ÷ 15 = 4.14 miles per kWh. An EV owner can now easily compare this to US-listed vehicles that advertise their efficiency in miles/kWh.

Example 2: A vehicle with 20 kWh/100km consumption converts to: miles/kWh = 62.137 ÷ 20 = 3.11 miles per kWh. This represents less efficient performance, useful for comparing lower-efficiency electric vehicles or larger SUVs.

Example 3: A highly efficient EV with 12 kWh/100km consumption converts to: miles/kWh = 62.137 ÷ 12 = 5.18 miles per kWh. This demonstrates exceptional efficiency, making it a top choice for cost-conscious EV buyers.

## Limitations

The converter assumes valid positive input values greater than zero, as negative or zero consumption values are physically impossible. The conversion is purely mathematical and does not account for real-world driving variations such as weather conditions, driving habits, road terrain, or vehicle load, all of which affect actual energy consumption. The output precision may vary depending on rounding; for scientific or engineering applications requiring extremely high precision, more decimal places should be retained. Additionally, this tool does not account for charging losses, which means the efficiency shown is the vehicle's consumption rate but not the total electricity drawn from the power grid.

## FAQs

**Q:** Why do different regions use different EV efficiency metrics?


**A:** Europe and much of the world use kWh/100km because it reflects consumption (how much energy you use), while the US uses miles/kWh reflecting efficiency (how far you go per unit of energy). Both convey the same information but from different perspectives.


**Q:** Is 4 miles/kWh considered good efficiency for an EV?


**A:** Yes, 4 miles/kWh is considered average to good efficiency for many modern EVs. Highly efficient vehicles like the Tesla Model 3 may achieve 4.2+ miles/kWh, while larger vehicles like SUVs typically achieve 3.2-3.8 miles/kWh.


**Q:** What's the relationship between kWh/100km and miles/kWh?


**A:** They are inversely related. Lower kWh/100km values (less consumption) correspond to higher miles/kWh values (better efficiency). The conversion factor 62.137 links them mathematically.


**Q:** Can I use this converter for fuel consumption metrics?


**A:** No, this converter is specifically for electric vehicles. Gasoline vehicles use different metrics like MPG (miles per gallon) or L/100km (liters per 100 kilometers), which require different conversion methods.
