There are three and a quarter light years in a parsec.
Electricity is converted into heat and light.
the conversions are solar to chemical to light to heat
It is hard to measure because light travels at such a high speed in one second that in one year, it would be too large a number to calculate. Try finding our the speed of light per second or minute and using conversions to calculate how many miles it would be. :)

Yes
A light year is a VERY LARGE NUMBER of miles, in either statute miles or in nautical miles. (A nautical mile is about 1.15 statute miles.) You can calculate it in either way, but the number will be enormous. one light year = 5.87849981 × 10^12 miles one light year = 5.10827668 × 10^12 nautical miles Did you know you can use Google for these calculations? Google has a great number of conversions available.

Electric current from the battery is converted to visible light and some heat in the bulb
None from the factory

A person can find weight conversions in several different places. Some of these places include Online Conversions, Scales Galore, and Metric Conversions.
