I know that 1 lbs=3500calories
but how many Newtons equal a kilogram and how many kilojoules equal a kilogram?
so basically what is N=kg=kj??
It's a bit confusing but I'm determined to finally fully learn metric... with some help ^_^
Thank you!

Consult any basic text on measurement or physics. The metric system is so much easier than the US system. Don't try to learn all the conversions. Learn to use the metric system on its own. There are a few helpful conversions to keep in mind - 1 m is a bit larger than 1 yard; 1 liter is a bit larger than 1 quart. 1 kg is a bit larger than 2 lbs.
The basic problem with Newtons and pounds is that they measure different properties. The metric system uses mass as the basic unit, while the US system uses weight.

I think you are confused about it.
Because a Newton N is a measurement unit for force eg 1 N = 1 kg*m/s^2.
Kilogram kg is a measurement unit for mass or weight.
And kiloJoule kJ is a measurment unit for work per energy.
Of what I know of math, it is impossible to connect the three units with the equal sign in between.

A newton is a measurement of force, a kilogram is a measure of mass - so "newtons" will never "equal" kilograms (similarly with kilojoules).
Having said that:
A newton is the amount of force required to accelerate a mass of one kilogram at a rate of one metre per second squared.
(Note the lowercase n in newton, but the symbol N is used as an abbreviation.)

you need to learn what the word UNITS means.
A Newton is a unit of force, and since force = mass x acceleration, a Newton is defined as the amount of force exerted on an object of unit mass due to unit acceleration. On the surface of our planet Earth, the acceleration due to gravity is 9.81 m/s^2. So in other words, the amount of force exerted on 1 kilogram of mass at sea level is 9.81 Newtons.
Kilojoules (kJ) are a unit of energy. Energy comes in many forms, but in the context of your question I would assume that it is pure mechanical energy, which is equal to force times distance. One joule is equal to one Newton times one meter (a force of 1 N applied at a distance of 1 m). A kilojoule is 1000 joules.

Not in the United States. We abolished any attempts to learn the metric system in our schools about 20 years ago. Too bad too. It makes us a 3rd world country. The rest of the world is metric. How backwards is that? Keep looking though. There are conversion tables all over the internet that will help you find real answers.

where im from we use the metric system, although im not that flash with your system. i know that a 2.2 pound is equal to 1 kilogram and 1000kg is 1 ton, 2.5cm is equal to one inch and dam my head hurts from al this maths so check out www.worldwidemetric.com this site has a conversion calculator and other stuff you might want to know

what's the imperial equipment? Oh like what we use interior the U. S., i did not understand the time period for it. I grew up utilizing imperial, yet ought to apply metric in math, so i'm fantastic with both yet i want imperial.

1N = approx. 10kg (P = m*g)
but KJ is hard to determine
