    15 Joule/Second to Megawatt

    Quick answer

    15 Joule/Second (J/s) equals

    1.500000e-5 MW

    To convert 15 Joule/Seconds to Megawatts, multiply by 1.000000e-6. Therefore, 15 Joule/Second (J/s) equals 1.500000e-5 Megawatt (MW).

    Formula: MW = J/s × 1.000000e-6. Calculation: 15 × 1.000000e-6 = 1.500000e-5 MW.
