Need help with Unit Coversions?

Question

I need to know how to convert units in to Newtons without the aid of computer or electronic device. In other words can you show me how to convert the following units to Newtons written and not a website were it will convert it for me. Kg, g, and l. Here is an example: 15.0kg to N

Answer 1

Of course you can convert kg to Newtons... kg = mass.
Mass (kg) x 9.81m/s² = Newtons.

N = kg x 9.81m/s²
15kg x 9.81 = 147.15 N
All other units MUST BE converted to mass in kg first.
1g = 0.001kg....0.001kg x 9.81 = 0.00981 N
I is Litres ?
With litres we're talking about volume, and volume can be in cc, mL, L, m³, Gallons ... etc. and in all cases Mass in kg is first required to obtain Newtons.

(Newtons ÷ 9.81 = Mass in kg).

...etc.

Answer 2

First, you can't convert kilograms to Newtons--they are different units. However, you can find the weight of something in Newtons by multiplying its mass by 9.8m/sec^2 That is, of course, for something on Earth. When you do that you will get a weight of 147 Newtons, that's because a Newton is the same as a kgm/sec^2

For grams you'd first one to convert to kilograms (by dividing by one thousand) and then again multiply by 9.8 m/s^2.

I have no idea what "I" is that you're referring to at the end.

Answer 3

Multiply your # of KG (ex 15) by 9.807 to get the # of Newtons

Convert g to KG and then multiply by 9.807

To convert Newtons to KG multiply the # of Newtons by 0.102
