Ok, I have an old drawing here and i need to convert this slope into degrees so i have a slop of 1:15 can anyone tell me the degrees??
Thanks for your help
Thanks for your help
I have not seen slops, I know it is early, of 1:15 but if it means for every 1 foot rise there is a 15 feet length, I would use use CAD or SOHCAHTOA, which ever was closest to hand.
.................or Google of course, which gave me this

3.8 degrees.
Consider it as a right angled triangle. If the length is along the hypotenuse then the sine of the angle you want is rise/length ie 1/15 = 0.0666666666666667 (0.0667) Use sine tables to find the angle. 3.8 degrees if I can use my calculator correctly
On a calculator, use inverse sine to get the answer. (3.8225 degrees), but I don't think this is the correct procedure -
The thing to be certain of is whether you are using the horizontal distance along the ground or the distance on the slope (eg the distance travelled).
Horizontal distance would use Tangent to calculate the angle. (3.814 degrees). I would use that to describe the gradient as in normal geometry it would be a ratio of horizontal to vertical, the answer would describe the slope of the hypotenuse.
Same here, if you have an android phone, get 'Visual Geometry Calculator'
Saves loads of messing about
Skew/mitre cuts expressed as xx mm skew on drawings gets me too. Our saw has degrees on it, not mm
SOME OF HARRY'S COW AND HORSES TROD ON ANDREW ... ANYONE BESIDES ME STILL GOT A DECENT WORKABLE SLIDE RULE???
whaaaa didn't realize it was in caps ......... it must be my age
The above replies confused me until I googled the initials link
