Unit Converters
Milliradians to Degrees Converter (mrad to °)
degrees = milliradians × (180/π) / 1000 ≈ × 0.0572958.
A milliradian is 0.001 rad ≈ 0.057296°. Optics, ballistics “mils,” and some scopes use mrad. NATO mil is often 1/6400 of a circle (~0.98175 mrad) — not this SI milliradian. Read the reticle manual.

When to use this Milliradians to Degrees
Common use cases
- A milliradian is 0.001 rad ≈ 0.057296°. Optics, ballistics “mils,” and some scopes use mrad. NATO mil is often 1/6400 of a circle (~0.98175 mrad) — not this SI milliradian. Read the reticle manual.
- Sanity-check with this case: 1 mrad ≈ 0.057296°. 17.4533 mrad ≈ 1°. A full circle is 2π×1000 ≈ 6,283.2 mrad.
- The relationship is: degrees = milliradians × (180/π) / 1000 ≈ × 0.0572958.

How to Convert Milliradians to Degrees Step-by-Step
- 1Enter Milliradians. Use the values you have, not a catalog average, unless that is all you know.
- 2degrees = milliradians × (180/π) / 1000 ≈ × 0.0572958.
- 3Worked case: 1 mrad ≈ 0.057296°. 17.4533 mrad ≈ 1°. A full circle is 2π×1000 ≈ 6,283.2 mrad.
- 4Check which dictionary the other person is using — US or UK, decimal or 1,024 — then trust the number.
Governing formula
degrees = milliradians × (180/π) / 1000 ≈ × 0.0572958.
1 mrad ≈ 0.057296°. 17.4533 mrad ≈ 1°. A full circle is 2π×1000 ≈ 6,283.2 mrad.
Example: set Milliradians = 1, then read the result.

- Degrees to ArcminutesSixty arcminutes in a degree. Survey bearings, astronomy declination, and map minutes all use this 60, not SI prefixes. 0.5° is 30′. A full turn is 21,600′.
- Degrees to Arcseconds3,600 arcseconds in a degree. Seeing of 1″, GPS, and IAU constants live here. 1/3600° is one arcsecond. Parallax of 1″ at 1 au defines the parsec.
- Degrees to GradiansA right angle is 100 gon (gradians), 90°, π/2 rad. Surveying in some countries still uses gon. A full circle is 400 gon. Do not mix gon and degrees in a bearing without saying so.
- Fahrenheit to Gas MarkAn American 350 °F cake is UK Gas Mark 4. The mark scale jumps about 25 °F per number. Round to the nearest mark your knobs actually have. Pizza steel at 500 °F is past Mark 9 — just use the number.
- Radians to Degreesπ rad is 180°. A full turn is 2π rad or 360°. Calculators in radian mode will ruin a trig exam if you type 90 thinking it is a right angle.
- Rankine to FahrenheitRankine is absolute Fahrenheit: 0 °R is absolute zero, and the degrees are the same size as °F. Subtract 459.67. Thermodynamics homework in US customary units lives here. 530 °R is about 70 °F.

Unit Converters
A 5K is 5,000 meters, not 5 kilometers on the nose if your watch is sloppy. Divide meters by 1,000. Track races, building plans, and “how far was that hike” all live in this split.
Feet to Meters
Unit Converters
US height, ceiling height, and lumber still arrive in feet. Meter plans do not. One foot is exactly 0.3048 m — not “about a third.” Use this when a listing says 10 ft ceilings and the architect works in meters.
Inches to Centimeters
Unit Converters
Monitor diagonals, waist measurements, and photo prints still come in inches. Clothing charts in Europe come in cm. Multiply inches by 2.54. That factor is exact, not a kitchen guess.

Very usable on mobile. Would love a save/export option later, but the math feels solid.
