What is a megajoule per second (MJ/s)?

Megajoule per second (MJ/s) is a power unit representing one million joules of energy transferred or converted every second, equivalent to one megawatt.

What does a femtowatt (fW) measure?

A femtowatt is an SI derived power unit equal to 10⁻¹⁵ watt, used to quantify extremely small rates of energy transfer typical in sensitive and nanoscale devices.

Why convert MJ/s to fW?

Converting from MJ/s to fW allows translating large industrial or energy production power values into very fine measurements suitable for analyzing ultra-low power signals or nanoscale energy dissipation.
