Car 150 hp = 150 / 1.36 ≈ 110 kW. Reverse: kW × 1.36 = hp
Metric (PS/hp) = 735.5 W. English (HP) = 745.7 W. The difference is ~1.4%. In Russia - metric.
Power (kW) × time (h) × tariff (rub/kWh) = cost. Heater 2 kW for 8 hours at a tariff of 6 rubles = 96 rubles.
The "2200W" vacuum cleaner is power consumption, not suction power. The actual useful power is usually 3–5 times less.
