What units does this use?

Standard SI units: Newtons (N) for force, kilograms (kg) for mass, and meters per second squared (m/s²) for acceleration.

No — a mass of 0 would make acceleration undefined (infinite) for any nonzero force, so the calculator requires mass above 0 when solving for acceleration.

What happens if I try to solve for mass with an acceleration of 0?

That's also not allowed — dividing force by an acceleration of 0 is undefined, so the calculator requires a nonzero acceleration when solving for mass.

Is this the same as weight?

Not exactly — weight is a specific case of force where acceleration is due to gravity (about 9.8 m/s² on Earth). This calculator handles the general F = m × a relationship for any force and acceleration, not just gravitational weight.

Can I use non-SI units like pounds or feet?

The calculator works in SI units (Newtons, kilograms, meters per second squared). Convert your values to SI units first if your problem is given in imperial units.
