<u>Time Units Conversion</u>
Sometimes we need to express magnitudes in different units, depending on the specific situation handled in the question or problem at hand. Magnitudes like length, time, mass, temperature, pressure, etc., can be expressed in several different units.
The most common units for time are years, months, days, hours, minutes, and seconds. There are 3,600 seconds in one hour and 24 hours in one day.
We are given the estimated age of the universe as 14 billion solar years. If one solar year is 365.25 days long, then the age, expressed in days is
14,000,000,000 * 365.25 days
Some quantities need to be expressed in scientific notation. This is the case since the numbers are too high
There are 24*3600=86400 seconds in one day, so
The estimated age of the universe is
