What is a Megawatt and a Ton of Refrigeration?

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

1 ton of refrigeration (TR) = 12,000 BTU/h = 3.517 kW = 3,024 kcal/h

Origin: Heat absorbed by melting 1 ton (2,000 lbs) of ice at 32°F in 24 hours

Note: The Megawatt is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Ton of Refrigeration 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

MW to kW converter → MW to Watts converter →

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 Ton of Refrigeration (TR)

How many tons of AC do I need?

Basic calculation: Square footage ÷ 400-600 = tons needed

More accurate method:

  1. Calculate BTU/h needed (sq ft × 20-25 BTU/h)
  2. Divide by 12,000 to get tons

Example (1,800 sq ft home):

  • BTU/h needed: 1,800 × 22 = 39,600 BTU/h
  • Tons needed: 39,600 ÷ 12,000 = 3.3 tons
  • Choose: 3 ton or 3.5 ton system

Factors affecting sizing:

  • Climate zone (hot = more, moderate = less)
  • Insulation quality
  • Window area and orientation
  • Ceiling height
  • Number of occupants
  • Heat-generating appliances

[AC sizing calculator]

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

Formulas:

  • BTU/h = Tons × 12,000
  • kW = Tons × 3.517

Examples:

  • 2 tons = 24,000 BTU/h = 7.03 kW
  • 3 tons = 36,000 BTU/h = 10.55 kW
  • 4 tons = 48,000 BTU/h = 14.07 kW
  • 5 tons = 60,000 BTU/h = 17.58 kW

Reverse:

  • BTU/h ÷ 12,000 = Tons
  • kW ÷ 3.517 = Tons

Tons to BTU/h converter → Tons to kW converter →

Why is it called a "ton" of refrigeration?

Historical origin: In the 1800s, ice production was measured by tons of ice produced.

The definition: 1 ton of refrigeration = cooling power needed to freeze 1 ton (2,000 pounds) of water at 32°F into ice in 24 hours.

The math:

  • Latent heat of ice: 144 BTU per pound
  • 2,000 lbs × 144 BTU/lb = 288,000 BTU in 24 hours
  • 288,000 BTU ÷ 24 hours = 12,000 BTU/h

Modern usage: The unit stuck even though we no longer use ice for cooling. It's purely a power measurement, NOT a weight!

What size AC for 2000 sq ft?

Typical: 3-4 tons (36,000-48,000 BTU/h)

Calculation (using 20 BTU/h per sq ft):

  • 2,000 sq ft × 20 = 40,000 BTU/h
  • 40,000 ÷ 12,000 = 3.33 tons
  • Result: 3-ton or 3.5-ton system

Climate adjustments:

  • Hot climate (Arizona, Florida): 4 tons (higher load)
  • Moderate climate: 3-3.5 tons
  • Cool climate (Northern states): 2.5-3 tons

Other factors:

  • Well-insulated home: Can use smaller (3 tons)
  • Poor insulation, lots of windows: Need larger (4 tons)
  • High ceilings: Add 10-20%
  • Multiple stories: May need multiple smaller units

Is bigger better for AC tonnage?

NO! Oversizing causes problems:

Issues with oversized AC:

  • Short cycling: Turns on/off frequently, wears out faster
  • Poor dehumidification: Doesn't run long enough to remove humidity
  • Hot/cold spots: Uneven cooling
  • Higher energy bills: Inefficient operation
  • Shorter lifespan: More wear and tear

Ideal sizing: AC should run 15-20 minutes per cycle, cycling 2-3 times per hour on hot days

Example:

  • 1,500 sq ft home needs 2.5-3 tons
  • Installing 5 tons would be wasteful and problematic
  • Better to size correctly or slightly undersize than oversize
