Alignment Sheet Nomenclature

Just got an alignment and I'm confused by the nomenclature used in the printout. For example, instead of using decimal points to express fractional numbers (e.g. -0.34), it uses a degree symbol and a hyphen (-034'). I've seen this before but never quite understood why the specs are expressed this way.

Because they are supposed to be measured in degrees. It's Zero degrees 34 seconds. Basically, at Zero. Say, how you gonna measure camber in decimals?

34 seconds??? Is that just 34 one-hundredths of a degree? If so, thats 0.34 degrees.

It's actually 0 degrees, 34 minutes and minutes/seconds can easily be converted to decimal notation and from decimal back to minutes/seconds. Here's a good explanation: Degrees, Minutes, Seconds | Zona Land Education

So, for my vehicle, the conversion is as follows (someone please confirm/deny):

Caster: 412' +/- 35' = 4.2 +/- 0.6
Camber:
Front: -030' +/- 1 = -0.5 +/- 1
Rear: -030' +/- 45' = -0.5 +/- 0.75

Toe for front and rear are given in inches, so no conversion necessary.

been 10 years since I was alignment tech but if I remember right most specs are in degrees. Usually it can be changed in the machine to show inches but there is no reason to do so.

I've never seen alignment specifications noted in anything but degrees.

Remember, you're dealing with angles and, as such, degrees are used.

Yes, it's minutes and seconds, not just seconds. Good reminder. either way.... Nothing wrong with the chart.
