Undergrad How Do SI and Imperial Units Relate in Weight, Density, and Gravity?
Frustrated and angry! I came to the physics forums to ask, what I thought, was a very straight forward question - obviously it wasn't. Like most people, I've been raised to think in Imperial (British) system, namely feet, pounds and seconds (where a pound is a measurement of weight). I am... -

Undergrad How Do SI and Imperial Units Relate in Weight, Density, and Gravity?
Does water = water? Ok, that's what I thought! So you would think that the SI water (water density * gravity) should equal the Imperial water (water weight * a conversion factor), right? Well, let's see... First, the Imperial side of the equation: If 1 m = 3.2808 ft then 1m^3 = 35.31... -

Undergrad How Do SI and Imperial Units Relate in Weight, Density, and Gravity?
Hello, I'm struggling to understand the relationship between SI units and Imperial units when it comes to weight, density and gravity. Using water as an example: I know that F = m g I also know that gravity is g = 9.81 m/s^2 or 32.174 ft/s^2 and that density of water is Pw =...
