Markus, when you wake up, what are you cooking up today with your new cookbook? Still trying to figure out unit conversions?

I got a lovely fluid mechanics problem that gave density in kg per cubic meter but then gave dimensions in feet and inches so I got to do lots of unit conversion. It gets pretty weird in dynamics problems turning miles per hour into feet per second and rpm into radians per second, psi into pounds-force per square foot, etc.

I always use slugs for mass, though. Pounds mass and pounds force are just way too confusing. 1 slug*ft/s^2 = 1 pound force but an object that weighs 1 pound force has 1 pound mass and an object with 1 pound mass experiencing 1 pound force experiences 32.174 feet/s^2 of acceleration. So, if F=ma, then 1/1=32.174?

It keeps things interesting though.
