It is chosen by humans only.

rest all constants such as G, $\epsilon _{o}$ are based on this.

k is proportionality constant.

Since, 1 unit force is defined as the mass of 1kg object produces the acceleration of 1m/s²

Therefore, 1 unit of Force = k x 1 kg x 1m/s²

Thus k = 1.

BY defining unit 1 newton we say that 1 newton is force that wn put a mass of 1kg to 1ms^-2 XLR8n

1N=k*1*1

so 1N=k

now F=ma newtons

please approve

The units are chosen such that k will be equal to 1

Force was not thought as a physical quantity when Newton published his laws of motion. So, Newton got the liberty to ‘define’ force and he did in such a way that it reduced complexity by making force unit the same as the product of mass unit and acceleration unit of the RHS side of the equation. Thus k became a dimensionless constant. Now, by putting m = 1, a = 1 and F = 1, we get k = 1.
