    KG force to newtons

    I am trying to work out newton force from a KG load. Do I just need to multiply it by 9.80665? The force I am looking at is water flowing horizontally, There is no fall, if I have 1000kg of water (1000 litres) of water moving horizontally is this equal to 9806 newtons?

    Yes,

    1 Kilogram force = 9.80665 Newtons..

    Not sure what your question is though... The weight of water?

    If you want the force of the water pushing forwards then you need to indicate velocity.

    1000 kg of water weighs 9.8x1000newtons

    1000kg oaf water moving with a velocity has momentum, not force.

    Force is the time rate of change of change of momentum.

    So you see that a still body of water only has the property of mass

    Force is needed to change it's momentum.

    Yup, but I think we are dealing with a very non-techy person here and it sounded like he wanted to know what he could push or had to hold back. "Force" seemed more appropriate in this instance.

    Yeah, but the concept of force in his context may be hard to explain, since we may not understand what he wants.
