Kilowatt (kW)
The kilowatt (symbol: kW) is a unit of power in the International System of Units (SI) equal to 1,000 watts:
1 kW=1,000 W
Kilowatts are widely used to measure the power consumption or output of household appliances, small engines, and electric tools. For example, a typical microwave oven might use about 1 kW of power.
In electricity billing, power usage is often measured in kilowatt-hours (kWh), which reflects energy consumption over time.
The kilowatt is a practical unit for everyday energy use, bridging the scale from watts (for small devices) to megawatts (for larger power generation). It helps people understand and compare the power ratings of common electrical equipment.
Femtojoule per Second [fJ/s]
Femtojoule per second is an ultra-small unit of power in the International System of Units (SI).
Femtojoule (fJ) equals 10−15 joules (0.000000000000001 joule).
When expressed as fJ/s, it measures the rate of energy transfer or work done at a scale of femtojoules every second.
Since 1 joule per second = 1 watt, then:
1 fJ/s=10−15 watts=0.000000000000001 watts
This unit is used in cutting-edge scientific research, including quantum mechanics, nanotechnology, and ultra-sensitive measurement instruments.
