Measuring, it’s quite fun (maybe Interesting is the better word, but for me it’s fun) when one has the tools. Electrical, Total Dissolved Solids in Water, Wind Speed – Direction – Amount of Precipitation – UV Light – Overall Light, Length of things, Diameter of things, etc.
So, being that I exercise by climbing the hill that my house is located on, usually descending to a point, then walking back up and past my house, I became interested in the Grade of the hill. I have a Samsung SM-R800 Watch and FitBit One that Measures the Barometric Pressure, and equates that to Altitude, and if, while walking, up stairs or up a sufficiently steep hill, I ascend 10’, I get credit for 1 Flight of Stairs Climbed. My hill is 9.85 Degrees near my house and at least as much, or more, for much of the hill. If I walk about 30 steps on the hill, I ascend 10’ (1 Flight), 60 is 20’ (2 Flights), 90 is 30’ (3 Flights), etc.
I originally calculated it by using a Yard Stick, and a Bubble Level, and with the one end of the Yard Stick on the Ground, the Level indicating that the Yard Stick is being held Level, I measured from the bottom end of the Yard Stick to Ground. So now I know that over 1 Yard (3’ or 36”), the change in Grade was 9.85 Degrees or 17.37%.
As the Images in this Blog Show, my hill rises 6.25” in 36”, so:
Everything is in the Same Unit of Measure (Inches in my case). 10’ is 120”.
Solving for X, is the Ratio of the Rise in Inches over the Horizontal Distance in Inches, Compared to the Desired Rise (but converted to Inches as 10’ x 12”=120” in my example) over the Unknown Horizontal Distance. Please note that I am Walking the Rise, not the Horizontal Distance, but this works adequately for my purpose. Technically, the Drawing Below, on the Right, is the Run vs Slope Lengths. For Every 3 Feet Horizontal Run, the Slope is 3’ 17/32” or roughly ½” Longer in 3’.
(36×120) / 6.5 = 664.62”. Convert Inches to Feet 664.62/12 = 55.38’ that I have to walk to climb 10’ in Elevation.
- 10 Feet in Rise = 56 Foot Walk
- 20 Feet in Rise = 112 Foot Walk
- 30 Feet in Rise = 168 Foot Walk
Due to variations in the Barometer Readings from Gusts and Wind, other Atmospheric Conditions, and the 17/32 more I need to walk on the Slope per 3’, it’s better to walk more than the required number of steps.
I do 30, 60, or 90 to get the Altitude, and with overshoot by going to, 35, 65, and 100 just to make sure I get the credit for the Flights of Stairs Climbed. Why more at 90? Because I get a little mad when I walk that far and the Watch only credits me with 2 Flights, better a little more distance, and it’s healthier as well.
Don’t get caught up in my meandering writing in this case, the purpose for this Blog Entry is Measuring Slope.
Now, I figured that there must be a simpler way, and there is. A Digital Level, the:
With this, all I need to do is set it on the Sidewalk, look around the Side, and Read the Degrees of Grade, Percent of Grade, or Inches Per Foot of Rise. Metric Readings are available as well. It cannot be tilted over to read the Display, it must be kept relatively square to the surface and the Display Read as it sits or the Display Indicates an Error (this is in the instructions). It has a Hold Button to keep the Reading so that you can pick up the Level and Read the Display.
It confirms my Calculations for the Degrees of Grade on my Street, in terms of Calculating the Grade, but it does all the Math for you automatically. Plus, it has the Standard Bubble Levels, one used on Upright Surfaces is absolutely amazing. It uses a Mirror so that it can be seen that the Level Bubble is Centered in the Lines by looking Down on the Top of the Level rather than Looking in from the Side. The Mirrors make it appear that there are two Level Bubbles, but it’s the same Bubble as Viewed from Two Mirrors, but it makes it easy to use.

Almost the Grade of my Hill. 30 Steps the Rise is 10 Feet, 60 Steps Rise is 20 Feet, and 90 Steps Rise is 30 Feet of Vertical Climb.
9.80 Degrees Shown, Can Also Display Percentage and Inches per Foot, and Metric.

Ingenious Level. Has Standard Bubbles, but has a Mirrored Opening that permits the viewing of the Vertical Bubble from the Top of the Level, as seen to the Left, otherwise you’d need to look around the side.
Measures Degrees of Grade, Percent of Grade, and Inches Per Foot Rise. Metric is available, and I believe other Units are available too.
The Measurements that are Displayed require the Level to be Upright, Held Square to the Ground, not tilted over on one Edge to read.

Sorry, my car got into the Scene.
LOL. Yeah Right!
Take a Yard Stick or Meter Stick. Use a Level on the Top, and Hold the Stick Level. Measure the Lower End of the Stick to the Ground, I used the Sidewalk, it’s usually the Same Grade as the Street and is Safer to Measure. Visit the Website Listed in the Blog, and Plug in the Measurements. Voila, this will give you the Grade in Percentage and Angle of Elevation. I had to set the Angle of Elevation Field to Degrees.
