Spec sheets quote different numbers in different regions. Enter one range value and instantly see what the same car scores on EPA, WLTP, NEDC and CLTC.
No accounts, no ads in the way, no waiting. The converter runs entirely in your browser so results update the instant you type.
Type once and read EPA, WLTP, NEDC and CLTC side by side. The standard you entered stays highlighted as your reference.
Switch units with a tap. Helpful when a European spec sheet meets a US buyer who thinks in miles.
Conversion ratios are drawn from average gaps across many production EVs, so you compare cars on equal footing.
Every region tests range differently. The same battery can earn wildly different numbers depending on the cycle, the temperature and the correction factor applied. Here's how they compare.
Combines city and highway cycles, then applies a conservative correction (around 0.7) to mirror everyday driving. Usually the lowest — and closest to what you'll actually see.
A four-phase, 30-minute cycle at 23°C covering city to highway speeds. More realistic than NEDC, but still optimistic versus real roads and cold weather.
A 1970s low-speed lab cycle, retired in Europe but still quoted in some markets. Numbers run high and rarely reflect modern driving.
Tuned to local urban driving with little high-speed running, so figures sit highest of all. Common on cars sold in China.
Type the number exactly as listed — for example, a 500 km WLTP rating or a 300 mile EPA rating.
Select WLTP, EPA, NEDC or CLTC so the tool knows your starting point. Set the unit to km or miles.
All four standards update at once. Use the EPA value as your most grounded estimate of real-world range.
An imported car rated 600 km CLTC isn't a longer-range car than a 480 km WLTP rival — it's often the very same range, measured differently. Converting makes that obvious.
