arcsecond to nanoradian
Convert arcsecond (″) to nanoradian (nrad). Use an editable angle converter, conversion formula, and reference table.
1 ″ = 4,848.136811 nrad
Conversion formula
One arcsecond equals 4,848.136811 nanoradian. Multiply your value in arcsecond by this factor to get nanoradian. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 arcsecond:5 × 4,848.136811 = 24,240.68406 nrad

About these measurements
An angle describes rotation between directions.
The base reference used here is the radian. One arcsecond is 0.000004848136811 base units; one nanoradian is 1e-9 base units.
Important distinctions
A full turn is 360 degrees or 2π radians. Signed angles are permitted.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
