Generally, NM (Newton Meter) is a force times the length of the arm. Bar is Pressure (force per unit of area). The conversion is not possible to calculate because of the difference in extensions (NM or N/m²).
However, in engine design the load of the engine can be given in bar (cylinder pressure) but converted into torque (N-m) by the following conversion: Cylinder Pressure (bar) =
Torque (N-m) * nrev * 2 * pi / Cylinder displacement (cubic meters) / 100,000
where: nrev = number of revolutions per cycle (2 for a 4-stroke engine, 1 for a 2-stroke)

What is the formula for moment of a force?
Turning moment (Nm) = Force (N) x Perpendicular Distance from the pivot to the line of action of the force (m)
What is NM cable type?
The NM represents the type of sheath on the cable. NM stands for Non Metallic sheath cable..
What is the formula to convert psi to bar?
One formula used to convert psi to bar is: 1 psi = (32.174 lbm /1 lbf s2)x(0.45359237 kg /1 lbm)x(144 in2/1 ft2)x(1 ft /0.3048 m) x(1 m s2 /105 kg) = 0.06894747 bar So 1 bar = 14.503795 psi The Math behind it. As psi is an imperial unit and bar is metric unit, we some constants 1 lb = 0.45359237 kg 1 ft = 0.3048 m 1 ft2 = 12 in x 12 in = 144 in2 And we have to rearrange some units 1 bar = 105 Pa = 105 Nm-2 And N = kg ms-2 so 105 Pa = 105 kgm-1s-2 Also note when applying newton's second law using imperial units we need to use a gravity constant 32.174 lbm /1 lbf s2 Metric m x a = F 1 kg x 9.81 ms-2 = 9.81 N Imperial units m x a = F 1 lbm x 32.174 fts-2 ≠ 32.174 lbf need to use gravity constant gc m x (a/gc) = F 1 lbm x (32.174 fts-2 / (32.174 lbm /1 lbf s2) = 1 lbf
How do you Convert Torque Nm to Force N?
Torque T=Nmsin x, thus Force N=T/msin x. If sin x is zero Torque is zero and Force is zero.
Prove that Emc2 is dimensionally correct?
E=mc^2 has units Newton meter (Nm). E=Nm and mc^2=(N/a)c^2 Nm= N(m/t)^2/m/t^2 = Nm. Thus Energy is unit equivalent to mc^2 and both are units of Nm.
