+1
P/W = "power to weight": as power goes up (keeping weight constant) = good
W/P = "weight to power" = the inverse of P/W: as power goes up (keeping weight constant) = bad

Unless you are saying that a lower number is going up, which is very weird...
So a 14:1 power-to-weight ratio for a typical family sedan, means it has to tote around 14lbs. of weight for every 1BHP the engine produces.
And by contrast, a 6:1 power-to-weight ratio for a Ferrari F430, means it only has to tote around 6 lbs. of weight for every 1BHP the engine produces.
You always want that number to go down. Down is good, up is bad.
A lower power-to-weight ratio improves bottom line performance and fuel economy.

What you are saying here is essentially W/P
