How accurate is the inclinometer?

Recommended Posts

How accurate do you suppose the inclinometer is that’s found in our off-road screen? I noticed on a few occasions during my trip out west last year from Ohio to West Yellowstone that when going up grades, it would only read 4% or so when going up a 6% grade. On the way down, sometimes it wouldn’t budge below 0%, unless it was something more drastic.

 

Not a huge deal, but I have a feeling mine is 2-3% off. Has anybody else seen the same or similar?

I could be wrong, but I think the truck inclinometer displays in degrees.   Roads are posted in % grade. 

 

(civil engineers and architects like to work with % grade)

DEGREES GRADIENT PERCENT
0.6° 1 : 95.49 1.0%
1 : 57.29 1.7%
1.15° 1 : 50 2%
1.19° 1 : 48 2.08%
2.86° 1 : 20 5%
4.76° 1 : 12 8.3%
7.13° 1 : 8 12.5%
10° 1 : 5.67 17.6%
14.04° 1 : 4 25%
15° 1 : 3.73 26.8%
26.57° 1 : 2 50%
30° 1 : 1.73 57.7%
45° 1 : 1 100%
56.31° 1: 0.67 150%
60° 1 : 0.6 173.2%
 63.43° 1 : 0.5 200%
78.69° 1: 0.2 500%
89.43° 1 : 0.1 1000%
90° 1 : 0

 

 

... and I  have not idea how accurate it is.

 

But 4 deg is about a 7% grade, according to this converter -

Face palm on my part...

 

This is usually the stuff I notice immediately, too. Makes perfect sense and I’m sure you’re right and that is the case with the readout being in degrees. Duh....

Mine never budged from 0. Now it’s flat as can be here other then overpasses, but even on those it don’t change.
