Dividing the light's power output by the effective area at the specified distance, we get
Intensity = P / A.
The power of light bulbs is measured in watts (W), which indicates the amount of energy consumed and the brightness of the light produced. The higher the wattage, the brighter the light emitted by the bulb.
Light bulb are measured in Candela (Cd) for its luminous intensity and Watt for its power consumed.
The wavelength of a light wave is typically measured using a device called a spectrophotometer or a spectrometer. These devices split the light into various wavelengths and measure them with detectors to determine the exact wavelength of the light wave. Wavelength can also be measured indirectly using the speed of light equation, where wavelength = speed of light / frequency.
The velocity of light was first measured by Ole Rømer, a Danish astronomer, in 1676. He used observations of the moons of Jupiter to deduce the finite speed of light.
Light energy is measured in units called photons. Photons are the smallest unit of light and are quantized particles that exhibit both wave-like and particle-like properties.
The electricity used by a Lightbuldb is measured in "Watts", the output of the Light (i.e. the Light) is measured in "Candela".
The amount of power they consume is measured in watts. The amount of light they put out is measured in lumens.
Stars are not measured in light years. The distance between them is.
Cheese quality is measured by the quality of milk and how long it was aged
In light speed.
Pressure.
Image quality, also known as print resolution, is usually measured in DPI-(dots per inch)
The power of light bulbs is measured in watts (W), which indicates the amount of energy consumed and the brightness of the light produced. The higher the wattage, the brighter the light emitted by the bulb.

They are measured in light years. Galaxies are often 100,000 light years across or more.
It is measured by length and diameter in millimeters. It is also "measured" by the quality of the cork itself.
