Wh/km (watt-hours per kilometre) is the efficiency readout on many EV dashboards, including Tesla vehicles and several BMS displays. It is simply kWh/100km scaled by a factor of 10: kWh/100km = Wh/km ÷ 10. A dashboard showing 150 Wh/km is reporting 15.0 kWh/100km.
Wh/km avoids decimal points in typical real-world ranges (roughly 120–250 Wh/km), making it convenient for live display. kWh/100km uses slightly larger numbers (12–25) but matches the scaling of L/100km, making side-by-side comparisons of petrol and EV energy cost straightforward.
For regulatory filings, manufacturer specifications, energy-cost calculations, and cross-car comparisons, kWh/100km is the standard. For live consumption data during a drive, Wh/km is often more practical. The two are arithmetically identical; only the scale differs.
Wh/km avoids decimal numbers in typical real-world ranges (100–250 Wh/km), making it convenient for live dashboard display. kWh/100km = Wh/km ÷ 10.
150 ÷ 10 = 15.0 kWh/100km. The factor 10 comes from: 1 kWh = 1000 Wh, and 1000 Wh/km ÷ 100 km = 10 Wh/km per kWh/100km.
Yes — watt-hours per kilometre, the energy consumed to travel each kilometre. It equals kWh/100km × 10, and km/kWh = 1000 ÷ Wh/km.
