Convert solar radiation from Joule per cm square to Watt per meter^2?

In summary, solar radiation can be converted from Joule per cm square to Watt per meter^2 by multiplying the value by 10000. The units of measurement for solar radiation can vary, but it is typically measured in Joule per cm square or Watt per meter^2. There is a difference between Joule per cm square and Watt per meter^2, with the former being a unit of energy density and the latter a unit of power density. Solar radiation is crucial for the functioning of solar panels, as it is converted into electricity through the photovoltaic effect. However, the measurement of solar radiation can be affected by factors such as location, weather conditions, time of day, and atmospheric conditions. It is important to consider these

I have solar radiation data in the units of Joule per cm^2 (joule per square centimeter) measured hourly. I want to use this data in evapotranspiratin calculation which requires radiation units as Watt per meter squared. How can I do this conversion?

## X \frac{joule}{cm^2 \, 3600 \, seconds}= X \cdot \, ( \frac{10^4}{3600}) \frac{joule}{m^2 \, sec} =X (\frac{10^4}{3600}) \frac{watt}{m^2}=[X (\frac{25}{9})]\frac{ Watt}{m^2}## . ## \\ ##
Note: 3600 seconds=1 hour ## \\ ##
So you multiply your number by ## \frac{25}{9} ## to get the value with the new units.

1. How do you convert solar radiation from Joule per cm square to Watt per meter^2?

To convert solar radiation from Joule per cm square to Watt per meter^2, you can use the conversion factor of 1 Joule per cm square = 10,000 Watt per meter^2. This means that you would multiply the value in Joule per cm square by 10,000 to get the equivalent value in Watt per meter^2.

2. Why is it necessary to convert solar radiation from Joule per cm square to Watt per meter^2?

Converting solar radiation from Joule per cm square to Watt per meter^2 allows for a more standardized and widely used unit of measurement. Watt per meter^2 is the standard unit for measuring solar radiation, making it easier to compare and analyze data from different sources.

3. What is the significance of using meters instead of centimeters in the conversion?

Using meters instead of centimeters in the conversion allows for a more accurate and precise measurement. Meters are a larger unit of measurement compared to centimeters, allowing for a more detailed and precise calculation of solar radiation.

4. Can you convert solar radiation from Joule per cm square to Watt per meter^2 using a calculator?

Yes, you can use a calculator to convert solar radiation from Joule per cm square to Watt per meter^2. Simply enter the value in Joule per cm square and multiply it by 10,000 to get the equivalent value in Watt per meter^2.

5. Is there a specific formula for converting solar radiation from Joule per cm square to Watt per meter^2?

Yes, the formula for converting solar radiation from Joule per cm square to Watt per meter^2 is: Watt per meter^2 = Joule per cm square x 10,000. This formula can be used to easily convert solar radiation measurements between these two units.
