Hello, probably stupid but cant find a reliable answer on Google.

I`m reading McCormac`s

on shear walls and i`m wondering how to translate the applied force in the calculation example on the shear wall to Newtons. Please see attached picture.

1 kN (kiloNewton) = 1 football player (approximately 225#)

If you're stuck on a conversion you can always take it back to the basics. I'm sure you know the conversion for lbs to kg, then our old friend gravity gets you to newtons.

kip = Kilo Pound??
Kilo being SI and pound being imperial?

Prefix from old greek
kilo = 1'000 (one thousand)
mega = 1'000 kilo = 1'000'000 (one million)
giga = 1'000 mega = 1'000'000'000 (one billion)
tera = 1'000 giga = 1'000'000'000'000 (one thousand billion)

see Standard ISO 1000 (now, probably, modified)

While kilo is associated with SI unit structure, it's not SI exclusively, since it's more for mathematical convenience
> micro-inches, mils (milli-inch)
> kiloton, megaton

kilo is a prefix for gram, kilogram. kilogram is actually the only base unit in the SI system that has a prefix.

1 kg * g (~ 10 m/s^2) = 1 Newtons. So Newton is actually kg*m/s^2.

I always remember from Arlo's song, "Coming in to Los Angelees; bringin' in a couple a keys", and the size of a key (=brick) at 2.2 pounds each.

Yep BUGGAR, 'keys' = 'kilos' = kilograms = 2.2 pounds. Not familiar with the song, though, and I probably don't want to be.

ThomasH : no ! any unit can have prefix "kilo" because means only "multiplied by 1'000". Tables I annexed are from "SI 1000" Standards.

Suggest you re-read ThomasH's post. His assertion that kg is the only SI base unit that is kilo-anything is correct.

[URL unfurl="true" said:
https://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication330e2008.pdf[/URL]]As an exception, the name of the kilogram, which is the base unit of mass, includes the prefix kilo, for historical reasons. It is nonetheless taken to be a base unit of the SI. The multiples and submultiples of the kilogram are formed by attaching prefix names to the unit name “gram”, and prefix symbols to the unit symbol “g” (see 3.2, p. 30). Thus 10−6 kg is written as a milligram, mg, not as a microkilogram, μkg.

Kilo is the troublemaker of SI. Aside from messing up the base unit of mass as above, it should also be upper case K like all the other >1 prefixes (and opposite the <1 prefixes).

Edit: forgot micro. Just use 'u' instead of a Greek character ffs

Never understood like this : to my understanding this is only for people not used to metric system (even if correct)
