What is a Metric Horsepower and a Kilowatt?

1 PS = 735.5 W = 0.7355 kW = 0.9863 hp (mechanical) = 75 kgf⋅m/s = 2,510 BTU/h

Names by region:

  • PS (Pferdestärke) - German
  • CV (Chevaux Vapeur) - French
  • pk (paardenkracht) - Dutch
  • hk (hästkraft) - Swedish
  • LE (Leistungseinheit) - Older German

All equal exactly 735.5 watts.

1 kW = 1,000 W = 1.341 hp = 3,412 BTU/h = 1,000 J/s

Note: The Metric Horsepower is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Kilowatt belongs to the imperial/US customary system.

Common Uses and Applications: PS vs kilowatts

Explore the typical applications for both Metric Horsepower (imperial/US) and Kilowatt (imperial/US) to understand their common contexts.

Common Uses for PS

Automotive: Engine power ratings in Europe, Asia (100-500 PS typical). Motorcycles: Engine power specifications (15-200 PS). Industrial: European motors, pumps, machinery (kW now more common). Marine: European boat engines, outboards (5-500 PS).

When to Use kilowatts

Appliances: Heaters (1-2 kW), microwaves (0.8-1.2 kW), electric ovens (2-5 kW). EVs: Charging power (3.7-22 kW home, 50-350 kW fast charging). Solar: Residential systems (5-10 kW capacity). HVAC: Air conditioner power (2-7 kW for homes).

Additional Unit Information

About Metric Horsepower (PS)

How do I convert PS to horsepower (hp)?

Formula: hp = PS × 0.9863 (or PS ÷ 1.014)

Examples:

  • 100 PS = 98.6 hp
  • 150 PS = 148 hp
  • 200 PS = 197 hp
  • 300 PS = 296 hp

Reverse: hp × 1.014 = PS

How do I convert PS to kilowatts?

Formula: kW = PS × 0.7355 (or PS ÷ 1.36)

Examples:

  • 75 PS = 55.2 kW
  • 100 PS = 73.6 kW
  • 150 PS = 110.3 kW
  • 200 PS = 147.1 kW

Quick approximation: Divide PS by 1.36 to get kW

What is the difference between PS and hp?

Metric HP (PS): 735.5 W (75 kgf⋅m/s, Europe/Asia) Mechanical HP (hp): 745.7 W (550 ft⋅lb/s, US/UK)

Difference: PS is 1.4% less than hp

Conversion: 1 PS = 0.9863 hp, 1 hp = 1.014 PS

Example:

  • BMW 330i: 258 PS = 254 hp = 190 kW
  • Ford Mustang: 450 hp = 456 PS = 336 kW

Modern trend: Manufacturers increasingly list all three (PS, hp, kW)

Why does Europe use PS instead of hp?

Historical: Metric system adoption in Continental Europe

Definition basis:

  • PS based on metric units (75 kg lifted 1 m in 1 s)
  • hp based on imperial units (550 lb lifted 1 ft in 1 s)

Current practice:

  • Official: kW is legal unit (EU regulations)
  • Marketing: PS still widely used in car advertising
  • Dual listing: Most specs show "kW (PS)" format

Example spec: "110 kW (150 PS)" on European car brochures

How do I compare engine specs in different units?

Three common formats:

  1. US/Canada: hp (horsepower mechanical)
  2. Europe/Asia: PS (metric horsepower)
  3. International: kW (kilowatts)

Quick comparison table:

| hp | PS | kW | |-----|-----|-----| | 100 | 101 | 75 | | 150 | 152 | 112 | | 200 | 203 | 149 | | 300 | 304 | 224 |

Conversion shortcuts:

  • hp ≈ PS (within 1-2%)
  • kW × 1.36 ≈ PS
  • hp × 0.746 ≈ kW

Example: Car rated at 184 PS = 181 hp = 135 kW (all same power)

About Kilowatt (kW)

How do I convert kW to horsepower?

Formula: hp = kW × 1.341

Examples:

  • 10 kW = 13.4 hp
  • 75 kW = 100.6 hp (100 hp)
  • 100 kW = 134.1 hp
  • 250 kW = 335.3 hp

What is the difference between kW and kWh?

kW (kilowatt) = Power (rate of energy use right now) kWh (kilowatt-hour) = Energy (total amount used over time)

Analogy:

  • kW = speedometer (speed right now)
  • kWh = odometer (total distance traveled)

Example: 2 kW heater × 3 hours = 6 kWh energy consumed

How much does 1 kW cost per hour?

Cost = kW × hours × electricity rate

Examples (at $0.15/kWh average US rate):

  • 1 kW for 1 hour = 1 kWh = $0.15
  • 2 kW heater for 8 hours = 16 kWh = $2.40
  • 100W light (0.1 kW) for 10 hours = 1 kWh = $0.15

Rates vary: $0.09-0.40/kWh depending on location and time of day.

How many kW is a typical home solar system?

Residential solar systems:

  • Small (2-4 people): 3-5 kW (10-15 panels)
  • Average home: 5-8 kW (15-24 panels)
  • Large home: 8-12 kW (24-36 panels)
  • Very large: 12-15+ kW (36-45+ panels)

Production: ~4-5 kWh per kW installed per day (varies by location, season).

Example: 6 kW system produces ~24-30 kWh/day, ~730-900 kWh/month.
