Calculator for the Planck Time

Conversion of different units of time to the Planck time.

The Planck time t_P is 5.391247^-44 seconds, which is the time it takes for light to travel one Planck length. This is an extremely short period of time, far shorter than anything that could be measured with the best instruments. For shorter periods of time, the laws of physics we know lose their validity. From one Planck time after the Big Bang, our universe can be described physically, the very first Planck time is called the Planck era or Planck epoch.
Please enter a period of time, this can also consist of several specifications, such as 3 minutes and 20 seconds. It will be calculated how many Planck times correspond to this input. ^ means to the power of. One year is counted as 365.2421875 days.

Example: the earth is about 4.6 billion years old, which corresponds to about 2.7 * 10^60 Planck times.
