My understanding is force and mass are two

**.***different things***is how much matter is in a body***Mass***is mass multiplied by an acceleration. Here on earth, that acceleration is 32.2 Ft/s2.***Force*Therefore, for the same

*mass*, there can be different forces depending on the acceleration.So, in English units,

*what is the mass of an 180 pound person, where 180 pounds is the force (F)?*i come up with:

**mass**= F/a = 180 lbs/32.2 Ft/sec2 = 5.59lbs-sec2/ft.Not sure what I am doing wrong

**Where have I gone wrong with the units?**

**What should be the proper unit for mass in english units?**

Looking on line, some examples just convert the 180 pounds to kg, and announce

**81.6kg**(180/2.2) as the answer.How can 81.6 kg be a

**when 180 pounds is a***mass***and not a***force***?***mass*Many thanks for the help
