Light intensity.
A rate that compares some quantity to one unit of another quantity is called a "unit rate." It expresses the amount of one quantity per one unit of another quantity, allowing for easy comparison and understanding of ratios. For example, if a car travels 150 miles on 5 gallons of gas, the unit rate would be 30 miles per gallon.
the physical quantity is distance and unit is meters
it is a unit rate
Unit rate
the formula showing the relation between the unit of any physical quantity n the unit of fundamental physical quantity is called dimensional formula.........of dat quantity

Lux is used in measuring luminous flux per unit area.
lux
The lux is the SI unit of illuminance, and is equal to 1 lumen per square meter.
A lux (lx) is the SI unit of iluminance, or light intensity as seen by the human eye.
LUX is the measurement of illuminance and luminous emittance from light sources.
A quantity is a numerical value that represents the amount or measurement of something, while a unit is a standardized amount used to measure that quantity. Quantity is the actual numerical value, while unit is the specific measurement scale used to quantify the quantity.
A standard use for a measurement of a physical quantity is called the unit of that physical quantity
The unit of measurement for the quantity represented by the keyword "m unit" is meters (m).
The quantity in unit rates refers to the amount or number being measured or compared in relation to a single unit of another quantity. It helps to determine the rate at which the original quantity is changing or occurring.
