What does one femtowatt represent?

One femtowatt (fW) is an SI derived power unit equal to 10⁻¹⁵ watt, used to measure extremely small rates of energy transfer.

How is joule/hour related to watt?

One joule per hour (J/h) quantifies energy transferred per hour and relates to watt by 1 J/h = 1/3600 watt.

Why convert femtowatt to joule/hour?

Conversion helps translate instantaneous power values into energy transfer averaged over time, useful in low-power and long-duration measurements.
