180000
There are 1000 micrograms in a milligram. You divide here by 1000. 15000/1000 will give you 15 milligrams.
Incandescent bulbs give about 10 lumens of light per watt of electric power Halogens give about 13 lumens per watt CFLs give about 50 lumens per watt So it depends on the type of bulb.
Yes, if they are the same type of lights, having twice as many lumens gives you twice as much light, regardless of how many lights you need.
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
It would depend on the wattage of the fluorescent tubes. As a rough estimate, you would need about 6-8 standard 40-watt fluorescent tubes to approximate the light output of a 1000-watt metal halide bulb.
1000 million light-years.
Thsi depends on the light bulb specification. For example if you buy a standard 60W light bulb from your supmarket then this will consume 0.06kilowatts. Its simple just divide the wattage stated on the light bulb by 1000 to give you the kilowatts
There are 1000 micrograms in a milligram. You divide here by 1000. 15000/1000 will give you 15 milligrams.
There are 1000 microlitres in a millilitre. Here, you multiply by 1000. 25x1000 will give you 25,000 microlitres.

1.5 billion stars per 1000 light years.
None at all.
Here you have to divide by 1000. 35/1000 will give you 0.035 grams
About 800 - 1000 give or take a few.
They really are not comparable. Light travels 186,000 miles per second, and one AU is about 8.3 light-MINUTES. You can probably do the math, from minutes to hours to days to years as well as I can. Or, you could google "1000 light years in AU" and get the answer
depends how many meatballs... 6 or 8
