Watts to Megawatts Conversion Calculator

Watts to Megawatts Calculator

Enter power in watts:

Megawatts result: MW

A Watts to Megawatts calculator converts power measurements between the base SI unit (watts, W) and the larger-scale unit (megawatts, MW). This conversion is essential for:
✅ Power plant operations
✅ Grid management
✅ Renewable energy projects
✅ Industrial power systems

---

Key Definitions

• Watt (W): Base SI unit of power (1 W = 1 joule/second)
• Megawatt (MW): 1 million watts (1 MW = 1,000,000 W)

Conversion Formulas

1. Watts to Megawatts

$$P(MW)=\frac{P(W)}{1,000,000}$$

Example:

• Convert 5,000,000 W to MW:

$$5,000,000÷1,000,000=5\text{ MW}$$

2. Megawatts to Watts

$$P(W)=P(MW)\times 1,000,000$$

Example:

• Convert 0.75 MW to W:

$$0.75\times 1,000,000=750,000\text{ W}$$

Conversion Table (W ⇆ MW)

Watts (W)	Megawatts (MW)
1 W	0.000001 MW
1,000 W (1 kW)	0.001 MW
10,000 W (10 kW)	0.01 MW
100,000 W (100 kW)	0.1 MW
1,000,000 W (1 MW)	1 MW
10,000,000 W (10 MW)	10 MW
100,000,000 W (100 MW)	100 MW

How to Use the Calculator

1. Enter Watts → Get MW (Divide by 1,000,000)

2. Enter MW → Get Watts (Multiply by 1,000,000)

Example Calculations:

• 250,000 W to MW:

$$250,000÷1,000,000=0.25\text{ MW}$$

• 1.5 MW to W:

$$1.5\times 1,000,000=1,500,000\text{ W}$$

---

Practical Applications

• Wind Turbines: A 3 MW turbine = 3,000,000 W
• Solar Farms: A 50 MW plant = 50,000,000 W
• Power Grids: A 500 MW station = 500,000,000 W
