Transform lbm.in/min² into Newton

Question

The units of physical quantities are important for the transformation of units, achieving coherence. So I need to transfom 10000 lbm.in/min² into N (Newton). But that's is not a trivial transformation, how do I could start this operation?

Answer 1

You should know the definition of the Newton in terms of kg, m and s$.

Loook up the conversions between 1 lbm and 1 kg, 1 in and 1 m, 1 min and 1 s.

Now you should be able to do the math and get the final result.
