How to Convert Picowatt to Megawatt

Converting Picowatt (pW) to Megawatt (MW) is a core calculation in Power, which measures the rate of energy expenditure, conversion, or work transfer per unit of time. Both units reside within the International System of Units (SI) and share an identical physical dimension vector ([M L² T⁻³]), separated strictly by a decimal order-of-magnitude factor (10^-18). Because this shift involves integer powers of 10, the conversion is mathematically exact and free from decimal rounding or irrational fractional loss. Exactly 1 Picowatt equals 1 × 10⁻¹⁸ Megawatt.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (watt (W)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 pW = 1 × 10⁻¹² watt (W)
2. Target SI Bridge (ktarget):1 MW = 1000000 watt (W)
Step-by-step substitution for Picowatt → Megawatt:V(MW) = V(pW) × ( 1 × 10⁻¹² / 1000000 ) = V(pW) × 1 × 10⁻¹⁸
Mathematical FormulaValue in Megawatt = Value in Picowatt × 1 × 10⁻¹⁸Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 75 pW, applying the conversion factor yields exactly 7.5 × 10⁻¹⁷ MW. At larger operational scale, 5000 Picowatt corresponds to 5 × 10⁻¹⁵ MW.

Inverse check: 1 MW = 1 × 10¹⁸ pW.

Frequently Asked Questions

The mathematical formula to convert picowatts to megawatts is: [value] * 1 × 10⁻¹⁸ = megawatts. Rather than doing the math manually, you can use our high-precision online calculator to process this exact equation instantly without rounding errors.

To perform the reverse calculation from megawatts back to picowatts, you must divide your starting value by 1 × 10⁻¹⁸. Our bidirectional tool automatically computes this inverse equation the moment you type into the megawatt input field.

1 Megawatt is larger than 1 Picowatt. Specifically, 1 Picowatt equals 1 × 10⁻¹⁸ megawatts, meaning 1 Megawatt is 1 × 10¹⁸ times larger than 1 Picowatt (a difference of 18.00 orders of magnitude). Expressing measurements in picowatts requires a larger numerical value to represent the equivalent physical magnitude.

A typical deep-space NASA Voyager probe radio signal power received by Deep Space Network dish measures 1 pW, which corresponds to 1 × 10⁻¹⁸ MW (Megawatt).

There are 1.00000 × 10⁻¹⁸ megawatts in 1 picowatt (1 pW = 1.00000 × 10⁻¹⁸ MW). Mega- denotes 10⁶ watts.

To convert picowatts (V(pW)) to megawatts (V(MW)), multiply by 1.00000 × 10⁻¹⁸:

V(MW) = V(pW) × 1.00000 × 10⁻¹⁸

For example, 4 × 10¹⁵ pW × 10⁻¹⁸ = 0.004 MW.

To convert megawatts (V(MW)) to picowatts (V(pW)), multiply by 1.00000 × 10¹⁸:

V(pW) = V(MW) × 1.00000 × 10¹⁸

For example, 1.2 MW = 1.20000 × 10¹⁸ pW.

Megawatts (10⁶ W) are used to express the power output of industrial diesel generators, large wind turbines, commercial locomotives, and data center infrastructure capacities.
