What is a femtowatt (fW)?

A femtowatt is an SI unit of power equal to 10⁻¹⁵ watts, measuring extremely small energy transfer rates, often used in nanoscale and sensitive electronic contexts.

What does decijoule per second (dJ/s) represent?

Decijoule per second is an SI-derived power unit equal to 0.1 watt, used to express relatively small power levels in scientific and engineering fields.

Why convert from femtowatt to decijoule per second?

Converting femtowatts to decijoule per second helps represent tiny power values in units scaled for manageable scientific measurement and clearer reporting.

Are there limitations in converting such small units?

Yes, converting femtowatts to decijoule per second leads to very small decimal values requiring careful measurement and representation to maintain accuracy.
