° to rad formula
The calculator converts the input to the category's reference unit, then divides by the target unit's factor.
Result = input × source factor ÷ target factor
1 × (0.0174532925199 ÷ 1) ≈ 0.017453293
Worked example: 1 Degrees ≈ 0.017453293 Radians
Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.

Definitions and assumptions
Angles are converted through radians. One full turn is 2π radians or 360 degrees. NATO, Swedish and former Soviet angular mils use different divisions and are separate units.

Frequently asked questions
how many rad is 1 °?
1 Degrees ≈ 0.017453293 Radians. Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.
how to convert ° to rad?
The calculator converts the input to the category's reference unit, then divides by the target unit's factor. 1 × 0.0174532925199 ≈ 0.017453293 Radians. Use the source and target factors shown in the formula. The worked example uses the value on this page, and the table provides other common values.
Why are there different angular mils?
Different conventions divide a turn into different counts, such as 6400, 6300 or 6000. Select the named convention instead of treating every mil as identical.
Why is the displayed result rounded?
Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.
What input range can I use?
This calculator accepts non-negative values up to 1 trillion, with up to 8 decimal places. It does not calculate signed vectors or calendar date intervals.
Why is a unit unavailable?
A conversion is unavailable when a verified unit definition or a current exchange-rate value has not been configured. The tool does not invent a coefficient.
