From W/cm² to ph:
As we know One W/cm² is equal to 683 ph (1 W/cm² = 683 ph).
To convert Watt/Square Centimeter (at 555 nm) to Phot, multiply your W/cm² figure by 683.
Example : convert 25 W/cm² to ph:
25 W/cm² = 25 × 683 ph = ph
To convert Phot to Watt/Square Centimeter (at 555 nm), divide your ph figure by 683.
Example : convert 25 ph to W/cm²:
25 ph = 25 ÷ 683 W/cm² = W/cm²
As we know One ph is equal to 0.0014641288 W/cm² (1 ph = 0.0014641288 W/cm²).
To convert Phot to Watt/Square Centimeter (at 555 nm), multiply your ph figure by 0.0014641288.
Example : convert 45 ph to W/cm²:
45 ph = 45 × 0.0014641288 W/cm² = W/cm²
To convert Watt/Square Centimeter (at 555 nm) to Phot, divide your W/cm² figure by 0.0014641288.
Example : convert 45 W/cm² to ph:
45 W/cm² = 45 ÷ 0.0014641288 ph = ph

ph. Since one W/cm² equals 683 ph, 9 W/cm² in ph will be ph.
There are 683 ph in one W/cm². In turn, one ph is equal to 0.0014641288 W/cm².
1 ph is approximately equal to 0.0014641288 W/cm².
The Watt/Square Centimeter (at 555 nm) value of 8 ph is W/cm². (i.e.,) 8 x 0.0014641288 = W/cm².
