What is a Megawatt and a BTU per Hour?

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

1 BTU/h = 0.293 W = 0.000293 kW

Key equivalents:

  • 3,412 BTU/h = 1 kW
  • 12,000 BTU/h = 1 ton of refrigeration = 3.52 kW
  • 1 BTU/h = 0.2931 W

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

Additional Unit Information

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)

About BTU per Hour (BTU/h)

How many BTU/h do I need for air conditioning?

Basic calculation: Room square footage × 20-25 BTU/h

Adjustments:

  • Sunny room: Add 10%
  • Shaded room: Subtract 10%
  • Kitchen: Add 4,000 BTU/h
  • More than 2 people: Add 600 BTU/h per person
  • High ceilings (>8 ft): Add 10-20%

Examples:

  • 200 sq ft bedroom: 4,000-5,000 BTU/h (5,000 BTU window unit)
  • 400 sq ft living room: 8,000-10,000 BTU/h (10,000 BTU window unit)
  • 1,500 sq ft home: 30,000-36,000 BTU/h (2.5-3 ton central AC)

[BTU/h calculator for HVAC sizing]

How do I convert BTU/h to watts or kW?

Formula:

  • Watts = BTU/h × 0.293
  • kW = BTU/h ÷ 3,412

Examples:

  • 12,000 BTU/h = 3,517 W = 3.52 kW (1 ton AC)
  • 24,000 BTU/h = 7,034 W = 7.03 kW (2 ton AC)
  • 10,000 BTU/h = 2,930 W = 2.93 kW (window unit)
  • 1,000 BTU/h = 293 W

BTU/h to Watts converter → BTU/h to kW converter →

What is the difference between BTU and BTU/h?

BTU = Energy (total heat/cooling) BTU/h = Power (rate of heating/cooling)

Analogy:

  • BTU = distance traveled (miles)
  • BTU/h = speed (miles per hour)

Example:

  • A 10,000 BTU/h air conditioner removes 10,000 BTU of heat per hour
  • Running for 3 hours removes 30,000 BTU total

Always use BTU/h when rating HVAC equipment capacity!

How many BTU/h equals 1 ton of refrigeration?

1 ton = 12,000 BTU/h = 3.52 kW

Origin: Based on melting 1 ton (2,000 lbs) of ice in 24 hours

Common AC sizes:

  • 1 ton = 12,000 BTU/h (small rooms, ~400-600 sq ft)
  • 1.5 tons = 18,000 BTU/h (larger rooms, ~600-900 sq ft)
  • 2 tons = 24,000 BTU/h (small homes, ~900-1,200 sq ft)
  • 2.5 tons = 30,000 BTU/h (medium homes, ~1,200-1,500 sq ft)
  • 3 tons = 36,000 BTU/h (larger homes, ~1,500-1,800 sq ft)
  • 4 tons = 48,000 BTU/h (large homes, ~2,000-2,400 sq ft)
  • 5 tons = 60,000 BTU/h (very large homes, ~2,400-3,000 sq ft)

How efficient is my furnace or AC?

Furnace efficiency (AFUE):

  • Old furnace: 60-70% AFUE
  • Standard: 80% AFUE (80,000 BTU/h input → 64,000 BTU/h heat output)
  • High-efficiency: 90-98% AFUE

AC efficiency (SEER):

  • Old AC: SEER 8-10 (inefficient)
  • Standard: SEER 13-14 (minimum new units)
  • High-efficiency: SEER 16-20
  • Ultra-high: SEER 20-26

EER (Energy Efficiency Ratio) = BTU/h output ÷ watts input

  • Good window AC: EER 10-12
  • Excellent: EER 12+
