For example a B737 has engines with 20k of thrust each which is about 2000 kgs of thrust in kilograms.
This is what happens when people have no tech background.
20 k of what ? I presume lbs, right ?
So that's 20,000 lbs of thrust, equivalent to some 9,000 kg, but more correctly, as thrust is a force, 88,200 N or 88.2 kN.
Then, total installed thrust, MSL / Standard conditions : 176.4 kN.
So, quite a lot more than you thought.
