Unit Conversions & Formulas

Power Conversions

1 kW = 1000 W | 1 kW ≈ 1.36 HP (Metric) | 1 HP ≈ 0.735 kW

Energy Conversions

1 kWh = 1000 Wh | 1 kWh = 3.6 MJ | 1 kWh = 3,600,000 Joules

Ohm's Law & Power Calculations

• For DC: Power (W) = Volts × Amps • For 1-Phase AC: Power (W) = Volts × Amps × Power Factor (default 0.9) • For 3-Phase AC: Power (W) = Volts × Amps × √3 (1.732) × Power Factor (default 0.9)

EV Consumption / Efficiency Conversions

• Wh/km = 1000 / (km/kWh) • kWh/100km = 100 / (km/kWh) • Between Wh/km and kWh/100km: 1 kWh/100km = 10 Wh/km

Area Conversions

• 1 m² ≈ 10.764 sq ft • 1 Hektar (ha) = 10,000 m² • 1 Acre (ac) ≈ 4046.86 m²

Speed Conversions

• 1 m/s = 3.6 km/h • 1 mph ≈ 1.609 km/h • 1 m/s ≈ 2.237 mph

Weight Conversions

• 1 kg ≈ 2.2046 lbs • 1 kg = 1000 g • 1 Metric Ton (t) = 1000 kg

Frequently Asked Questions (FAQ)

What is the difference between kW and kWh?

kW represents power (instantaneous charging speed or motor output), while kWh represents energy (total battery capacity). For example: kW is the speed at which water flows, while kWh is the amount of water collected in a bucket.

How is electric vehicle (EV) efficiency measured?

EV consumption is typically measured in kWh/100 km (lower is better) or km/kWh (higher is better). For instance, 15 kWh/100 km means the vehicle uses 150 Wh of energy to travel 1 kilometer.

What is the difference between AC and DC charging?

AC (Alternating Current) charging is slower (typically 3.7 kW to 22 kW) and uses the vehicle's onboard charger. DC (Direct Current) charging is fast (50 kW to 350+ kW) and feeds power directly into the battery.

Does temperature affect EV range?

Yes. Cold weather slows down chemical reactions in the battery and increases heating usage, which can temporarily reduce an EV's driving range by 20% to 30%.
