Parkinson's disease is a progressive nervous system disorder that can cause tremors in the hands and arms, rigid muscles and speech changes such as slurring, according to the Mayo Clinic. â
Electric power law: P = V x I   P = power in watts   Einstein's law: E â¦ = m x cÂ²   E = energy in joules, m = mass in kilograms, and c is the speed of light.
How to convert luminous flux in lumens (lm) to electric power in watts (W) .You can calculate watts from lumens and luminous efficacy.umens to watts calculation formula. The power P in watts (W) is equal to the luminous flux Ï V in lumens (lm), divided by the luminous efficacy Î· in lumens per watt (lm/W): P (W) = Ï V(lm) / Î· (lm/W). So. watts = lumens / (lumens per watt).
