Why do the scientist use scientific notation to measure in the universe?

Using basic units from the SI system,
- the nearest star to the sun is approx 40,218,000,000,000,000 metres away.
- the furthest known galaxy is 126,800,000,000,000,000,000,000,000 metres away.
- the mass of the sun is 1,989,000,000,000,000,000,000,000,000,000 kilograms.
- the mass of the Milky Way Galaxy is approximately a trillion times as large.
It is easier to make mistakes when working with such large numbers. Furthermore, in many cases, the numbers are known to only few significant digits so the trailing zeros are no more than place holders. That is why scientific notation is so useful.

Do architects use scientific notation?
Yes, architects use scientific notation to do the calculation of the measurement of either very long/short (or both) objects. They use scientific notation to save time, writing out the whole term, such as 14324141240123.... or 50000000... Basic geometry is also applied to their careers since they need to learn how to measure the lengths of the shapes and lines! It's quite interesting that architects use math!
Why Kilometre is not a convenient unit to measure distances in the universe?
You can use kilometer, but end up with fairly large numbers, which are best written in scientific notation. It is quite possible to deal with those, but perhaps due to a lack of familiarity of the general public with scientific notation, light-years and parsecs are often used instead. When using these units, you end up with smaller numbers. For example, the distance to the nearest star (after the Sun) is about 4.2 light-years; each light-year is about 9.5 x 1012 km, that is a 13-digit number if you write it out.
What is the difference between significant figures and exponent notations?
Significant figures is a way of trying to convey how accurately something is being measured. A very accurate scale may measure .001 grams, a bathroom scale may be only accurate to within 2 lbs. Exponential notation has nothing to do with measurement. It is just a choice on how to write a number, usually for some mathematical application. 243 = 35 this is exponential 'notation'. Scientific notation is a certain type of exponential notation in which the base must be 10. 243 = 2.43 x 102 that is scientific notation.
Who uses scientific notation in every day life?
• Scientific notation is used by the astronomers for their calculation of distance, speed, revolution of the planets around the sun. • The meteorologic department who have to calculate the changing weather. • Electrical engineers for their trigger operations which has ten thousand operations per second. • The players of chess games to see the number of all possible games. • Physicists use it to measure the distance between particles. • Geologists use it to measure the age of rocks.
What is 'e' in viscosity measurement while measure in exapoise eg 1exapoise equals 1e plus 20?
This looks like the commonly used shortcut for scientific notation. 1e20 or 1e+20 is the same as 1 x 1020.
How does a scientist answer a scientific answer?
Observes and measure
What is the largest measure of scientific notation?

Smallest measure of scientific notation?
There is no such concept.
How does a scientist answer scientific question?
Observes and measure
How is magnitude and scientific notaion related?
The exponent in scientific notation is a measure of the order of magnitude.
How do you measure stars with scientific notation?
It depends on what you want to measure: their numbers, distance, mass, temperature, ...
What is one way scientist use to calculate the age of the universe?
Measure the distance from Earth to nearby stars.
What unit do you use to measure the mass of the earth?
With scientific notation, the kilogram does the job just fine.
What is the measurement used to measure distance in space?
Distance in space is measured in 'light years' or in 'scientific notation'
What scientific tool do scientist use to measure volume?
You would use a graduated cylinder
7.02 mL converted to scientific notation cm?
There can be no equivalence - whether or not scientific notation is used! A centimetre (cm) is a measure of length in 1-dimensional space while millilitre (mL) is a measure of area in 3-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
What is 25 kilograms in meters?
25 kilograms in scientific notation is 2.5 × 101kg
