Watts per squ meter?
In summary, Watts per Square Meter (W/m<sup>2</sup>) is a unit of measurement used to describe the amount of power (in watts) per unit area (in square meters). It is commonly used in scientific and engineering fields to measure the intensity of energy or heat flux. It is calculated by dividing the power (in watts) by the area (in square meters) and is used to measure solar radiation, heat flux, power output, and electromagnetic radiation. In climate science, it is used to understand the Earth's energy balance and its role in global climate change. Some common misconceptions about Watts per Square Meter include thinking it is a measure of temperature and assuming a higher number always means more heat without considering the type

Are you guys conducting half of this conversation over AIM and the other half at PF? This thread makes absolutely no sense.

I decided that a question which made no sense deserved an answer to match.

Why aren't you asking your question yet!?
What is Watts per Square Meter (W/m2)?
Watts per Square Meter (W/m2) is a unit of measurement used to describe the amount of power (in watts) per unit area (in square meters). It is commonly used in scientific and engineering fields to measure the intensity of energy or heat flux.
How is Watts per Square Meter calculated?
Watts per Square Meter is calculated by dividing the power (in watts) by the area (in square meters). The formula is W/m2 = W / m2, where W represents watts and m2 represents square meters.
What are some common examples of Watts per Square Meter?
Some common examples of Watts per Square Meter include solar radiation from the sun, heat flux from a fireplace or heater, and power output from electronic devices such as light bulbs or laptops. It is also used to measure the intensity of electromagnetic radiation, such as radio waves or microwaves.
How is Watts per Square Meter used in climate science?
In climate science, Watts per Square Meter is used to measure the amount of solar energy that is absorbed by the Earth's surface and atmosphere. This helps scientists understand the Earth's energy balance and how it contributes to global climate change.
What are some common misconceptions about Watts per Square Meter?
One common misconception is that Watts per Square Meter is a measure of temperature. However, it is a measure of power per unit area and does not directly correlate to temperature. Another misconception is that a higher number of Watts per Square Meter always means more heat. While this can be true in some cases, it also depends on the type of energy being measured and the context in which it is used.
