I'm doing a physics problem and I can't remember how to convert kilograms into Newtons. Help!

simply multiply the weight (if in kilograms) by the acceleration. Newtons is a unit of force and F=ma.

There is no way to convert kilograms into newtons, they are two different units. Kilograms is a scalar unit of mass where Newtons is a vector unit of force.
If you want to find somethings weight in Newtons and you have its mass in kilograms, you can use Newton's Second Law F = ma where a is the acceleration of gravity, m is mass in kilograms and F is weight (force) in Newtons.

Kilograms are units of mass and Newtons are units of force. You can't just simple from mass to force (or weight).
Use Newton's first law: F=m*a
where a: acceleration and m: mass in kg
If it's a falling object on the Earth, then a = gravitaional acceleration = 9.81 (m/sec)/sec
Also, just think of 1 N = 1kg*m/sec^2

W = mg = 422 Newtons, where W is the force of gravity, which we call weight. m = the mass in kg of the object that weighs 422 N; and g = 9.81 m/sec^2 the acceleration due to the gravitational force W near Earth's surface. Thus m = W/g = 422/9.81 which is a bit more than 42 kg; you can do the math. The physics is this...gross weight is proportional to the mass of the object being weighed. And the proportionality constant g is about 9.81 m/sec^2 near Earth's surface. Note that mass remains fixed at m, but the weight W can vary if g varies. For example, g on the Moon is 1/6 that value on Earth; so that, for the same mass m, the weight is W/6 = mg/6 on the Moon.

The S.I. unit of force is newton and in solving physics problems only the S.I. unit should be used.
S.I unit of force is newton . A practical unit of force is kilogram weight.
One kilogram weight= 'g' newton = 9.8 newton

I was looking to convert a measurement the other day, and came across a handy webpage, click the link below (converts to newtons, I checked ;-) )....

I assume you are talking about kilogram-force.
1kg = 10 newton approx. or better, 1kg-force = 1kg-mass x 9.81 m/s^2 = approx. 10 newton

if you have a mass in kilograms, multiply by 9.81 =g (m/s^-2)
so 1 kg is 1*9.81 = 9.81N
