Default meaning of slope angle (eg. 1:50)

In lesson MET19, slope angles are mentioned of warm & cold fronts.

I understand that 100% slope is 45?, but for my understanding what is the meaning (in degrees) when mentioning the slope in units, such as 1:50, 1:100, 1:150 ? (Is this 23, 45 & 68? ?)

Thx,
BS

Default Re: meaning of slope angle (eg. 1:50)

Hello,

The way I've always understood it is as a ratio, so for a slope of 1:50 it slopes downwards at a rate of 1 unit vertically to 50 units horizontally or with units 1000ft downwards per 50,000ft (8.2NM) across. You can change the units as much as you like so long as you begin with the same ones to start with (can then convert accordingly). If you think of it like that you can also understand better how a slope of 1:150 is shallower than a slope of 1:50

Hope that helps!
