Can someone tell me how to convert watts into wm-2?
cheers
Do you mean that you need to convert $\displaystyle [W]$ into $\displaystyle \left[\frac{W}{m^{2}}\right],$ where $\displaystyle m$ is meters?
If this is the case, then you're going to need to provide more context. What problem is this for? Can you state the problem statement exactly?
If Akbeet is correct and you are trying to convert from Watts to "Watts per meter squared" then you need to divide by an area- "meters squared". You cannot convert a single number from "Watts" to "Watts per meter squared"- they measure different things. "Watts" is a measure of power and "Watts per meter squared" is a measure of the intensity of that power spread over some area.
Hello, ohdearthisisheadrot!
Can someone tell me how to convert watts into w/m^2 ?
Isn't that the same as asking:
. . How to convert miles into miles per hour?
. . How to convert pounds into pounds per square inch?
. . How to convert dollars into dollars per ounce?

You see, we know the conversion: .1 dollar = 100 pennies.
. . So we can convert dollars to pennies.
My example was: How to convert miles to miles per hour.
Imagine! . "A car drove 200 miles. .What was its speed?"
. . Silly, isn't it?
Obviously, we need a "conversion".
. . $\displaystyle \begin{array}{cccccc}\text{For example:} & \text{200 miles} &=& \text{2.5 hours} \\
\text{Then:} & \text{80 miles} &=& \text{1 hour} \end{array}$
. . And the car's speed is 80 miles per hour.
Without a conversion, we can always ask unanswerable questions:
. . A bottle of L'amour perfume costs $300.
. . . . . What is its cost per ounce?
