Today, we are going to discuss the "Angle Conversion and calculation formulas for degrees, minutes, and secondsHere is a note about "The

 

In the course of designing a machineDegrees, minutes, and seconds are also used in the backlash of rotating structures.Also, mechanical backlash is often expressed in "minutes" or "seconds" for angles of 1 degree or less because "degrees" is too much.

 

There are some useful websites for calculating degrees, minutes, and seconds, but this is a basic overview. Please use it to understand the definitions of degrees, minutes, and seconds, and the differences between them.

Conversion and calculation formulas for the nomenclature of angles "degrees, minutes, and seconds

Degrees, minutes, seconds

Basic "angles" explained

Angle is a quantity or measurement that expresses the magnitude of an angle, and there are "degrees, minutes, and seconds" as units for angles.

English: measure of angle or angle

 

 

What is the unit of angle "degree"?

The angle to the center of an arc that divides the circumference into 360 equal parts.

 

Nomenclature in SI units: 1° = (π/180) rad

Definition of a degree: the angle to the center of an arc that divides the circumference of a circle into 360 equal parts

 

 

What is the unit of angle "minute"?

One minute is 1/60th of a degree, and one minute is 1/21600th of an arc.

 

Nomenclature in SI units: 1′ = (1/60)° = (π/10 800) rad

Definition of minutes: (1/60) degrees

Symbol: ′ (Prime)

 

 

What is the unit of angle "second"?

One second is 3600th of a degree, and one second is 1296000th of an arc.

 

Nomenclature in SI units: 1″ = (1/60)′ = (π/648 000) rad

Definition of seconds: (1/60) minutes

Symbols: ″ (double prime)

 

 

Summary of how to calculate degrees, minutes, and seconds (formulas)

Here, I will go over how to convert degrees, minutes, and seconds, and note the formula for the conversion.

 

 

convert a degree to a minute

Minute = degree*60

Example: 54 degrees to the minute, 54*60 = 3240 minutes

 

 

Convert degrees to seconds

Seconds = degree*3600

Example: To convert 54 degrees to seconds, 54*3600 = 194400 seconds

 

 

Convert minutes to seconds

Seconds = minutes * 60

Example: 54 minutes to seconds: 54*60 = 3240 seconds

 

 

convert minutes to degrees

Degree = min/60

Example: 54 minutes to a degree is 54/60 = 0.9 degrees

 

 

Convert seconds to degrees

Degree = sec/3600

Example: 23 seconds to a degree is 23/3600 = 0.0064 degrees.

 

 

Convert seconds to minutes

Minutes = seconds/60

Example: To convert 23 seconds to minutes, 23/60 = 0.383 minutes

 

 

Find degrees, minutes, and seconds together in degrees.

Example: 45 degrees, 54 minutes and 23 seconds to the degree is 45 + (54/60) + (23/3600) = 45.906 degrees

 

The above is the formula for calculating degrees, minutes, and seconds.

 

That's it.
