What Is This Tool?
This converter transforms values from shake, a very small informal time unit used mainly in nuclear physics, to the sidereal second, a unit based on Earth's rotation relative to the fixed stars, essential in astronomy and space sciences.
How to Use This Tool?
-
Enter the time value in shakes.
-
Select 'shake' as the input unit and 'second (sidereal)' as the output unit.
-
Click convert to get the equivalent time in sidereal seconds.
Key Features
-
Converts from shake (10 nanoseconds) to second (sidereal).
-
Supports precise bridging between nuclear physics timing and astronomical time standards.
-
Browser-based and easy to use for high-precision interdisciplinary timing conversions.
Examples
-
5 shakes = 5 × 1.0027379155284e-8 = 5.013689577642e-8 second (sidereal)
-
100 shakes = 100 × 1.0027379155284e-8 = 1.0027379155284e-6 second (sidereal)
Common Use Cases
-
Specifying event timing in nuclear detonation and reactor physics experiments.
-
Calculating sidereal time for astronomical coordination and telescope tracking.
-
Supporting space-flight attitude control and celestial navigation with sidereal time.
Tips & Best Practices
-
Use this converter for theoretical or scientific applications requiring high timing precision.
-
Remember that shakes are informal and not an SI standard unit.
-
Account for the small difference between sidereal seconds and international SI seconds in precise work.
Limitations
-
Shakes are informal and extremely small, lacking official SI standardization.
-
Sidereal seconds are slightly different from SI seconds, affecting precise conversions.
-
This tool suits mainly high-precision scientific or astronomical contexts, not general timing.
Frequently Asked Questions
-
What is a shake in time measurement?
-
A shake is an informal time unit equal to 10 nanoseconds, mainly used in nuclear physics and engineering to describe very short intervals.
-
What is a sidereal second?
-
A sidereal second is 1/86400 of a sidereal day, representing Earth's rotation relative to fixed stars, used in astronomy and related fields.
-
Why convert shakes to sidereal seconds?
-
This conversion relates extremely short nuclear timing intervals to sidereal time used in astronomy and space sciences, bridging different precision domains.
Key Terminology
-
Shake
-
An informal time unit equal to 10 nanoseconds, used primarily in nuclear physics for very short interval measurements.
-
Second (sidereal)
-
A unit of time equal to 1/86400 of a sidereal day, representing Earth’s rotation relative to distant stars.
-
Sidereal Day
-
The period of Earth's rotation measured relative to fixed stars or vernal equinox, different from the solar day.
