📐 Your Comprehensive Guide to Angle Conversion
Welcome to the ultimate resource for understanding and converting between different units of angular measurement. While "degrees" are the most common unit, various fields like mathematics, engineering, and physics use others such as radians, gradians, and even percent slope. Our powerful angle converter is designed to handle all these conversions seamlessly, making it an essential tool for students and professionals.
Understanding the Core Angle Units
To use an angle converter effectively, it's important to know what each unit represents. Our tool instantly converts between all of these:
- Degrees (°): The most familiar unit. A full circle is divided into 360 degrees.
- Radians (rad): The standard mathematical unit for angles. A radian is the angle subtended at the center of a circle by an arc that is equal in length to the radius. A full circle is 2π radians. Our tool is an excellent radian to angle converter.
- Gradians (grad): Also known as "gons," this unit divides a right angle into 100 parts, making a full circle 400 gradians. It's often used in surveying.
- Turns (rev): The simplest unit, where one full circle or revolution equals 1 turn.
Specialized Converters for Every Need
This tool goes beyond basic conversions with specialized tabs for common tasks.
The Degrees, Minutes, Seconds (DMS) Converter
Just like an hour is divided into minutes and seconds, a degree can be subdivided for higher precision. This is crucial in cartography and astronomy. Our angle converter for degrees, minutes, and seconds makes this simple:
- 1 Degree (°) = 60 Arcminutes (')
- 1 Arcminute (') = 60 Arcseconds (")
Use our "DMS" tab to instantly convert a decimal value like 45.505° into its DMS equivalent (45° 30' 18") and back.
The Percentage to Angle Converter
In fields like construction, civil engineering, and even for a custom solar mounting angle converter, slope is often expressed as a percentage. This represents the "rise over run" as a percentage. Our percentage to angle converter (and vice-versa) uses trigonometry to switch between these formats:
- Angle to Percent:
Percent = tan(Angle in Degrees) × 100
- Percent to Angle:
Angle in Degrees = atan(Percent / 100)
This tab also includes conversion to a ratio format (e.g., 1:12), common in roofing and design.
A Note on "Wide Angle Converters" in Photography
Many users searching for an "angle converter" are looking for information about photography equipment. It's important to clarify the difference:
This tool is a *mathematical* angle converter, not an *optical* one.
A wide angle converter lens is a secondary lens that screws onto the front of a camera's primary lens to increase its field of view. It essentially makes your lens "wider," allowing you to capture more of the scene. This is different from converting a unit like degrees to radians.
Understanding Photography Converters
- Function: They work by optically compressing a wider scene onto your camera's sensor. A typical wide angle converter might have a magnification factor like 0.7x or 0.45x.
- Popular Brands & Models: You'll find options from major brands like a Sony wide angle converter (e.g., for the a6000 series) or from third-party manufacturers like Vivitar. There are also brand-specific converters for popular cameras, such as the Fuji X100 wide angle converter or the Ricoh GR III wide angle converter.
- Lens Sizes: These converters attach to the filter thread of your existing lens, so you must match the size, such as 58mm or 37mm. They are a popular accessory for kit lenses like the Canon 18-55mm.
- Software vs. Hardware: A `normal photo to wide angle converter` app uses software to digitally stretch and warp an image to simulate a wider view, which often results in a loss of quality. A physical lens converter is a hardware solution that captures a genuinely wider field of view.
While our tool doesn't alter photos, it helps you understand the very "angles" that define a lens's field of view!
❓ Frequently Asked Questions (FAQ)
Q1: How do you convert degrees to radians?
A: The conversion formula is: Radians = Degrees × (π / 180)
. Our calculator does this for you instantly.
Q2: What is a turn?
A: A "turn" (or revolution) is one complete rotation around a circle. 1 turn = 360° = 2π radians = 400 gradians.
Q3: How many degrees are in a 25% slope?
A: Using our "Slope / Percent" tab, you can quickly find that a 25% slope is equal to approximately 14.04 degrees.
