How do you convert W m2 to J?

How do you convert W m2 to J?

The formula used to convert W/m² to Joule per Second per Meter² is 1 Watt per Meter² = 1 Joule per Second per Meter².

How do you convert mW cm2 to MJ cm2?

Light energy at the test material surface is a measure of cumulative intensity exposure (UV light intensity x time), quantified as millijoules/cm2 and is simply: mW/cm2 x seconds = mj/cm.

How is J cm2 measured?

The wavelength of a laser determines it’s color and absorption properties. Dosing: most common dosing technique in laser therapy is the energy density delivered to the surface of the tissue which is typically expressed in J/cm2. Coherence: The photons within a laser beam are extremely well organized and directional.

What is µW cm2?

Power density is defined as power per unit area. For example, power density can be expressed in terms of milliwatts per square centimeter (mW/cm2) or microwatts per square centimeter (µW/cm2). One mW equals 0.001 watt of power, and one µW equals 0.000001 watt.

What is J m2?

Joule/square meter ↔ Joule/square centimeter Conversion. J/m2: :J/m2.

How do you calculate UV light irradiance?

Light power (mW) was measured with a (power meter) sensor area of 70.89×10-6 (m2). Then the irradiance of this light from UV lamp was calculated by dividing the light power with sensor area to get its irradiance in W/m2.

How many Joules are in a milliwatt?

Milliwatt to Joule/second Conversion Table

How do you calculate energy per pulse laser?

Another example: if your 500 W laser has a 200 ms pre-programmed pulse duration, that will give you 500 W * 0.2 s = 100 J of total energy. The total energy can be controlled by modulating the pulse width/duration.

What is uW m2?

microWatts/Square Meter. (µW/m2) microWatts/Square Centimeter.

What does uW m2 mean?

Micro-Watts per square meter
uW/m2 = W/m2 x 1,000,000 (Micro-Watts per square meter = Watts per square meter times one million)
