Direct answer
EV Range Converter gives an instant result from your inputs. This EV Range Converter helps you compare electric vehicle range values across the most common testing standards: WLTP, EPA, NEDC, and CLTC. Formula snapshot: The converter uses NEDC as a baseline and applies fixed conversion ratios between standards. Example: NEDC: 600 km -> WLTP: 510 km (estimated).
About this calculator
This EV Range Converter helps you compare electric vehicle range values across the most common testing standards: WLTP, EPA, NEDC, and CLTC.
Because these standards use different test cycles and assumptions, the same vehicle can show different range numbers in each system.
Use this tool to get quick cross-standard estimates when researching imported EV models, reading mixed-spec listings, or comparing reviews from different regions.
How it works
A quick explanation of the logic behind the results, so you can trust what you see.
- The converter uses NEDC as a baseline and applies fixed conversion ratios between standards.
- From NEDC baseline: WLTP = NEDC x 0.85, EPA = NEDC x 0.85 / 1.168, CLTC = NEDC x 0.85 / 0.82.
- When you enter a value in any source standard, the tool first normalizes to NEDC and then computes target standard estimates.
Formula used
These are the core formulas and logic rules used by this calculator.
- The converter uses NEDC as a baseline and applies fixed conversion ratios between standards.
- From NEDC baseline: WLTP = NEDC x 0.85, EPA = NEDC x 0.85 / 1.168, CLTC = NEDC x 0.85 / 0.82.
Common use cases
Below are common real-world scenarios where this calculator is useful.
- Comparing EV specs from US, Europe, and China listings
- Converting WLTP values to EPA-style estimates before buying
- Checking realistic expectation gaps between standards
- Creating side-by-side EV comparison sheets
- Researching imported EV models with mixed documentation
How to use
- Select the source standard (WLTP, EPA, NEDC, or CLTC).
- Enter the EV range value in kilometers.
- Review converted estimates for all standards in the result cards.
- Use the formulas shown in each row to understand how values were converted.
Common mistakes to avoid
These are the issues that most often cause confusing results.
- Treating converted values as guaranteed real-world mileage.
- Mixing miles and kilometers without unit conversion first.
- Assuming all manufacturers report under the same test standard.
- Comparing two EVs without confirming source standard labels.
Tips and notes
- Always keep units consistent in kilometers when using this converter.
- Use converted values for comparison guidance, not exact trip planning.
- Check weather, speed, terrain, and battery age for real-world range expectations.
- For public listings, display both source and converted standards for clarity.

Glossary
Quick definitions for common terms used in this calculator.
WLTP
Worldwide Harmonized Light Vehicles Test Procedure, widely used in Europe.

FAQ
Is this EV range conversion exact for every car?
No. It provides standard-to-standard estimates. Real-world range varies by driving style, weather, speed, and battery condition.
Which standard is usually closest to real-world usage?
EPA is often considered more conservative than NEDC and CLTC, but actual results still vary by driver and route.
Can I convert in reverse (for example EPA to WLTP)?
Yes. Select EPA as input, enter the value, and the tool computes all other standards automatically.
Does this converter support miles?
This version uses kilometers. Convert miles to kilometers first for accurate cross-standard output.
Is this calculator free to use?
Yes. This calculator is free to use without signup.
Can I use this calculator on mobile?
Yes. The calculator is mobile-friendly and works on desktop as well.
Are the results exact or estimates?
Results are based on the formulas and inputs shown on this page. For high-stakes decisions, verify with official or professional sources.
What should I check if my result looks wrong?
Check unit selection, date format, decimal inputs, and whether all required fields were entered correctly.
