Distances in space are measured using light years, which represent the distance light travels in one year. This unit is used because space is vast and traditional units like kilometers or miles are too small to accurately measure these distances.
Light bulb are measured in Candela (Cd) for its luminous intensity and Watt for its power consumed.
The refractive index is measured by comparing the speed of light in a vacuum to its speed in a material. Common methods for this measurement include using a refractometer, spectrometer, or interferometer.
The brightness of light bulbs is typically measured in lumens. Wattage can also be used as a general indicator of brightness, but lumens provide a more accurate measurement of the actual amount of light produced by a bulb.
Opacity can be accurately measured using a device called a nephelometer, which measures the amount of light scattered by particles in a substance. This measurement provides a quantitative value for the opacity of the substance.
Distances in space are measured using a variety of methods, such as parallax for nearby stars, radar for planets in our solar system, and redshift for galaxies and other objects in the universe. These measurements help astronomers understand the scale of the universe and the vast distances between objects in space.
Usually such distances are measured either in light-years, or in parsecs.

parsecs or light years
The distance between planets are measured in millions of kilometers while the distance between solar systems are measured in light years while the galxies and the universe are measured in AU (astronautical units)
Light Year is unit for all astronomic distances
Stellar distances are measured in light-years, which is the average distance between the Earth and the Sun.
usually lights are measured in lumens
No, a kilometer is not the longest distance; it is a unit of measurement equal to 1,000 meters. While it is commonly used to measure distances, there are much larger units such as miles, light-years, and astronomical units that represent greater distances. For example, a light-year, which is the distance light travels in one year, is significantly longer than a kilometer.
You can use astronomical units or light years.
since you measure space in light years, not very acurate. Distances in space are as accurate as the tools by which they are measured.
Yes, a light year would be useful in a model of the solar system to represent distances between celestial objects, as it is a unit of measurement that denotes the distance light travels in a year. This can help convey the vast scales and distances involved in the solar system.
