first of all i want to know whats mean by gon

2- i need to convert 22g 68c 33cc into degrees minutes seconds and plz explain to me how did u convert it and whats c and whats cc

and at last thx for this forum who helped me alot last year

no gon is something to measure angles and sometimes it is called grades gon is 1/400 of circle degree is 1/360 of circle i just googled it and now iam ok with converting gon to degrees but i dont know how to convert the "c" and the "cc" into minutes and seconds "c" and "cc" fractions of the gon

Gradian -- from Wolfram MathWorld

Quote:

Gradian

A unit of angular measure in which the angle of an entire circle is 400 gradians. A right angle is therefore 100 gradians. A gradian is sometimes also called a gon or a grade.

Almost all calculators have a key identified as [DRG].

[Degrees_Radians_Grads]. You can switch very quickly between the units.

A grad (or gon) is a decimal form for angular measure.

A right angle, or 1/4 of a circle, is 90 degrees.

90 degress is $\displaystyle \cfrac{\pi}{2}$ radians.

A right angle, or 1/4 of a circle, is 100 grads.

1 grad = 0.01 of a right angle;

1 metric minute = 1c = 0.01g ( 1/100 of a grad )

1 metric second = 1cc = 0.01c ( 1/100 of a metric minute, or 1/10000 of a grad)

convert 22g 68c 33cc into degrees minutes seconds

0.226833 of a quarter circle

$\displaystyle 0.226833 \times 90\text{degrees}=20.41497 \text{degrees}$

Simply convert the decimal-degrees into the degrees-minutes-seconds required.

Hope that helps.

.

NOTE: c & cc were originally defined as circular measure. It could be stated as 1.57rad for 1.57 radians or 1.57c , meaning circular measure. The c & cc gradually became associated with the 0.01 grad & 0.0001 grad.
