Lumens measure the brightness of a light source, while kelvin measures the color temperature. Lumens indicate how bright the light is, while kelvin indicates the color appearance of the light, such as warm or cool.
Lumen measures the brightness of light, while kelvin measures the color temperature of light. Lumen indicates how bright a light source is, while kelvin indicates the color appearance of the light, such as warm or cool.
Kelvin measures the color temperature of light, indicating whether it is warm or cool. Lumens measure the brightness of light, indicating how much light is emitted.
Brightness tells you the temperature and mostly temperature would tell the brightness of the star that we are talking about.
As temperature increases the absolute brightness increases
A thermocouple is a device that measures temperature by detecting changes in voltage when there is a difference in temperature between two different metals. When one end of the thermocouple is heated or cooled, it creates a voltage that is proportional to the temperature difference. This voltage is then converted into a temperature reading by a thermometer or temperature controller.

The thermometer is used to measure temperature whether it air, water, molten steel, anything you can think of. Scales of measuring Temperature are mainly Celsius , Fahrenheit and Kelvin
A thermocouple measures temperature difference between two points, producing a tiny voltage corresponding to the difference in temperature. To measure temperature with a thermocouple, you need to know the temperature of one junction and calculate the difference from the table or equation for the type of t/c used. An RTD changes resistance in response to temperature--to measure temperature with an RTD you measure its resistance (usually by putting a known voltage across it and measuring the current).
The difference between centimeters and inches is that inches is in the standard measuring system and centimeters is part of the metric measuring system.
The 100W light bulb is brighter than the 60W light bulb. The difference in brightness is 40 watts.
The correct spelling is "Celsius." Celsius is a unit of measurement for temperature, named after the Swedish astronomer Anders Celsius. It is commonly used in scientific and everyday contexts to measure temperature. "Celcius" is a misspelling of Celsius and does not have any specific meaning or usage in measuring temperature.
