What is a BTU per Second and a Megawatt?

1 BTU/s = 1,055.06 W = 1.055 kW = 3,600 BTU/h = 1.41 hp = 0.001055 MW

1 MW = 1,000,000 W = 1,000 kW = 1,341 hp = 3.412 million BTU/h = 0.001 GW

Note: The BTU per Second is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Megawatt belongs to the imperial/US customary system.

Common Uses and Applications: BTU/s vs megawatts

Explore the typical applications for both BTU per Second (imperial/US) and Megawatt (imperial/US) to understand their common contexts.

Common Uses for BTU/s

Rare Unit: Almost never used in practice. Theoretical: Engineering textbooks, conversion tables. Alternatives Preferred: MW for large systems, BTU/h for HVAC. Historical: Old power plant references (now use MW).

When to Use megawatts

Renewable Energy: Wind turbines (2-15 MW), solar farms (1-100 MW). Power Generation: Small power plants, gas turbines, diesel generators. Industrial: Large factories, manufacturing plants, mining operations. Data Centers: Hyperscale facilities (20-100 MW), server farms.

Additional Unit Information

About BTU per Second (BTU/s)

How do I convert BTU/s to kW or MW?

Formula:

  • kW = BTU/s × 1.055
  • MW = BTU/s × 0.001055

Examples:

  • 100 BTU/s = 105.5 kW = 0.106 MW
  • 1,000 BTU/s = 1,055 kW = 1.055 MW
  • 10,000 BTU/s = 10,550 kW = 10.55 MW

BTU/s to kW converter → BTU/s to MW converter →

How do I convert BTU/s to BTU/h?

Formula: BTU/h = BTU/s × 3,600

Examples:

  • 1 BTU/s = 3,600 BTU/h
  • 100 BTU/s = 360,000 BTU/h
  • 1,000 BTU/s = 3,600,000 BTU/h (3.6 million BTU/h)

BTU/s to BTU/h converter →

Why not use BTU/s for power plants?

Megawatts clearer: 500 MW vs 473,900 BTU/s International standard: MW used globally Simpler calculations: Metric system easier Industry convention: All power plants rated in MW or GW

Example: Nuclear reactor

  • As MW: 1,000 MW (clear, concise)
  • As BTU/s: 947,800 BTU/s (unwieldy)
  • As BTU/h: 3.41 billion BTU/h (also unwieldy)

MW is the practical choice for large power systems.

About Megawatt (MW)

How do I convert MW to kW or W?

Formula:

  • kW = MW × 1,000
  • W = MW × 1,000,000

Examples:

  • 1 MW = 1,000 kW = 1,000,000 W
  • 5 MW = 5,000 kW = 5,000,000 W
  • 2.5 MW = 2,500 kW = 2,500,000 W
  • 0.5 MW = 500 kW = 500,000 W

How many homes can 1 MW power?

Average US home: ~1.2 kW average (30 kWh/day ÷ 24 hrs)

1 MW = 1,000 kW

Calculation: 1,000 kW ÷ 1.2 kW/home ≈ 833 homes (average load)

Regional variations:

  • High AC use (Arizona, Texas): ~600-700 homes
  • Moderate climate: ~700-900 homes
  • Mild climate: ~900-1,200 homes

Peak vs average:

  • Average load: 1 MW = 800-900 homes
  • Peak load (summer afternoon): 1 MW = 300-500 homes

Example: 5 MW wind turbine powers ~4,000 homes on average

What is the difference between MW and MWh?

MW (Megawatt) = Power (rate of energy use/generation right now) MWh (Megawatt-hour) = Energy (total amount over time)

Analogy:

  • MW = speedometer (speed right now)
  • MWh = odometer (total distance traveled)

Example:

  • 5 MW solar farm × 6 hours = 30 MWh energy produced
  • 10 MW data center × 24 hours = 240 MWh daily consumption

Power plant ratings: Always in MW (capacity) Energy production/consumption: Measured in MWh or GWh

How much does a 1 MW power plant produce per year?

Formula: Annual MWh = MW × hours/year × capacity factor

1 MW at 100% capacity: 8,760 MWh/year (365 days × 24 hours)

Realistic production (accounting for capacity factor):

Nuclear: 1 MW × 8,760 hrs × 90% = 7,884 MWh/year Coal: 1 MW × 8,760 hrs × 50% = 4,380 MWh/year Wind: 1 MW × 8,760 hrs × 35% = 3,066 MWh/year Solar: 1 MW × 8,760 hrs × 25% = 2,190 MWh/year

Example: 5 MW wind turbine produces ~15,330 MWh/year (~1,700 homes)

How big is a 1 MW solar farm?

Solar panel efficiency: ~400W per panel (modern, 2024) Panels needed: 1,000,000 W ÷ 400 W = 2,500 panels

Land area:

  • Fixed tilt: 4-5 acres per MW
  • Single-axis tracking: 6-8 acres per MW
  • Dual-axis tracking: 8-10 acres per MW

1 MW solar farm typical specs:

  • Panels: 2,500-3,000 (400W each)
  • Land: 5-7 acres
  • Annual production: 1,500-2,500 MWh (depending on location)
  • Homes powered: ~150-250 homes

Scaling: 100 MW solar farm = 500-700 acres (varies by location, technology)
