Light intensity or irradiance
Paper is weighed in GSM (grams per square meter)
1 kg per square meter = 1.84 lbs per square yard 1 lbs per square yard = 0.54 kg per square meter
Divide by 9.81
The conversion factor is 33.91 so multiply 4.75 by 33.91 to get grams per square meter. (4.75 oz. per square yard = about 161.052301 grams per square meter).
10.76391 square feet per square meter.
Sound intensity is measured in watts per square meters, but our eardrums are only moved by the sound pressure measured in newtons per square meters or pascals.
Power P is measured in watts and intensity I (power per area) is measured in power per square meter if you think e.g. of sound.
Energy: joulesPerhaps you mean power: that would be joules/second = watts Intensity is measured in watts per square meter.
No.
The sound intensity is defined as the sound power per unit area and is measured in watts per square meter. But our ears are sensitive only to the sound pressure, measured in pascals or newtons per square meters. Scroll down to related links and look at "Table of sound levels".

Your ears and the sound pressure level meter "measure" the sound pressure of a sound wave. Sound intensity is measured in watts per square meter.Intensity is measured in watts per square meter.Note: Sound power (sound intensity) is the cause -and the sound pressure is the effect.The effect is of particular interest to the sound engineer.
Watts is a unit of power (energy per time). Square meter is a unit of area (length squared). These units are not convertible between each other.
The best technology so far (2015) gives about 150 Watts per square metre.
That's not a special kind of light - you can do that with any light. The power per area (e.g., watts per square meter is a measure of INTENSITY.
The intensities of traveling waves, which includes sound, light, etc., are measured in units of power divided by area. That is, watts per square meter (W/m2 ) or watts per square foot (W/ft2), or any combination of units which is equivalent.
Pressure is measured in pascal, which is the pressure of 1 newton over 1 square meter. (A newton is the amount of force needed to accelerate 1 kilogram by 1 meter per second per second. In the English system, pressure is measured in pounds per square inch. A pound per square inch is equal to about 6,890 pascal.
