Can someone tell me how to convert watts into wm-2?
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.
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".
. . 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?
