However, when you go to countries that use kilograms instead of pounds, knowing the conversion rate helps you know how much to purchase to get the same amount regardless of measurement scale. Knowing the cost per kilogram, instead of per pound, also helps you calculate how expensive it will ...
How much gas is generated by a plasma converter? That depends on what you put into the furnace. If the garbage contains a lot of carbon-based material (in other words, organic waste), then you'll get more gas. Waste with a lot of inorganic material won''t yield as much gas. Because...
These 10-pound (4.5-kg) darts are 2 feet (61 cm) long, approximately 1 inch (2.5 cm) in diameter and leave the barrel of the tank's cannon traveling at over 1 mile (1.6 km) per second. The dart has so much kinetic energy and is so strong that it is able to pierce the ...

A computer in a house uses 0.3 kilowatt for 18.9 hour. If electricity costs $0.23 per kilowatt-hour, how much does it cost (in dollars, to the penny) to use the computer per day? Use exact numbers; do not estimate. Estimate how much work is req...
A pound of tin is worth $2 more than a pound of copper. Three pounds of tin are mixed with 7 pounds of copper to make bronze that sells for $3.85 per pound. How much is a pound of tin worth? A metallurgist has one alloy containing 32...
How much does 1 kg of plutonium cost? Since the energy per fission from plutonium-239 and uranium-235 is about the same, the theoretical fuel value of fissile plutonium can be put at $5,600 per kilogram. Reactor-grade plutonium also contains non-fissile isotopes, reducing its value to abou...
Fast fact:How much is a trillion cubic feet? Enough to fill a cube with sides two miles long! Note:Equipment operates at varying efficiencies. These conversion factors are strictly for the commodity, and efficiency factors are not included....
NASA's goal is to reduce launch cost to only a few hundred dollars per pound within the next 25 years. They believe one way to do that is to dump the more than a million pounds of liquid oxidizer that is currently needed for combustion. "Air-breathing rocket engine technologies have the...
This is due to several distinct disadvantages associated with these systems. The first is the high capital investment when compared with soil farming. Though hydroponics is typically much cheaper over time, it does require a substantial upfront cost to establish any sort of larger system. Next, ...
