kg as Force?
kg as Force?
(OP)
A prospective customer is apparently asking our sales folks for wind load data in kg. In this context, do you suppose they mean kN/g or is it likely to be a typo?
I'm not sure where they are located... somewhere in Asia, I think... perhaps Indonesia.

RE: kg as Force?
For buildings (and most everything), wind is always given in force/area units based on a wind speed.
If you have a fixed type of equipment, with a fixed area and shape...such as a bundle of lights at the top of a pole, then you might have a design wind load in terms of just force. But ultimately, this is based on a force/area quantity.

Apparently the RFQ says "wind load: kg"

You might try searching the sight on several terms associated, e.g. units, kg, m/kg, metric are a few that come to mind that might bring you to these threads.
Some very knowlegable people helped me with this issue, since I was not raised nor educated in a kg system.

kn is a unit of force in the SI system.
the difference being gravity.

Just to be safe, I've given the number in lb and kg just so there's no confusion. If they're expecting kN then they can convert it.

In the MKS system, the kilogram is STILL a unit of mass, not force.
However, I have seen many engineering calculations from Europe (France and Germany in particular) and Japan, which use the kilogram weight as a unit of force.
One kilogram weight is the force acting on a 1 kilogram mass under 1 g of acceleration (approximately 9.807 m/s/s).

RE: kg as Force?
Thanks, I stand corrected. I realized over the weekend that I have stated it incorrectly. But Kg, nevertheless, is used(missused!) as a unit of force, e.g. 300Kg/cm² for concrete strength.

So long as the context is clear, there shouldn't be any issue, particularly if your calculations do the dimensional analysis correctly.
