How to Convert Planck Time to Day
1 None = 6.23907407407407e-49 d
Example: convert 15 None to d:
15 None = 15 × 6.23907407407407e-49 d = 9.35861111111111e-48 d

Planck Time
Planck time is the theoretical minimum meaningful unit of time, approximately 5.39 × 10^-44 seconds, representing the time it takes for light to travel one Planck length in a vacuum.
History/Origin
Introduced by physicist Max Planck in 1899 as part of his system of natural units, it arises from fundamental constants and marks the scale at which classical ideas about gravity and space-time cease to be valid, requiring a quantum theory of gravity.
Current Use
Primarily used in theoretical physics and cosmology to describe phenomena at the Planck scale, and as a fundamental unit in models of quantum gravity; it is not used in everyday measurements.
Day
A day is a unit of time representing the period of one complete rotation of the Earth on its axis, typically lasting 24 hours.
History/Origin
The concept of a day has origins in ancient civilizations observing the cycle of day and night. The 24-hour day was standardized in the modern era, with the division into hours dating back to ancient Egypt and further refined through the adoption of mechanical clocks.
Current Use
The day is used universally to measure time intervals, schedule activities, and organize daily life, with the 24-hour system being the standard in most countries worldwide.
