Kilosteradians to yoctosteradians converter

Formula

Worked example

Convert 1 ksr to ysr:

1 ksr ≈ 1e+27 ysr

Multiply your ksr value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

What kilosteradians measure

Kilosteradians (ksr) represent solid angle. One unit equals 10^3 sr. A steradian is the solid angle that subtends an area equal to radius squared on a sphere.

Reading the result in yoctosteradians

Yoctosteradians (ysr) represent solid angle. One unit equals 10^-24 sr. A steradian is the solid angle that subtends an area equal to radius squared on a sphere.

Where this conversion helps

Convert a solid-angle quantity between decimal scales. A complete sphere subtends 4π steradians. Solid angle cannot be treated as a plane angle in radians.

How the scale changes

The input unit has a factor of 1e3 sr; the output unit has a factor of 1e-24 sr. Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.

Reading very small or large results

Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
