How do you convert measurements into scientific notation?
To convert any number into scientific notation, you write the non-zero digits, placing a decimal after the first non-zero digit. Then, you count the number of digits you need to move the beginning decimal to get to where your decimal is now. If you move the decimal to the left, then your power is positive.

What is this μm?
micrometre, also called micron, metric unit of measure for length equal to 0.001 mm, or about 0.000039 inch. Its symbol is μm. The micrometre is commonly employed to measure the thickness or diameter of microscopic objects, such as microorganisms and colloidal particles.
What is scientific notation?
Scientific notation is a way to express numbers as the product of two numbers: a coefficient and the number 10 raised to a power. It is a very useful tool for working with numbers that are either very large or very small.
How far is the Sun from the Moon?
Astronomers are accustomed to very large numbers. While the moon is only 406, 697 km from earth at its maximum distance, the sun is much further away ( 150 million km). Proxima Centauri, the star nearest the earth, is 39, 900, 000, 000, 000 km away—and this is just the start of long distances.
What is the power of 10?
The coefficient is the 1.5 and must be a number greater than or equal to 1, and less than 10. The power of 10, or exponent, is 11 because you would have to multiply 1.5 by 10 11 to get the correct number. Scientific notation is sometimes referred as exponential notation.
What does a positive exponent mean?
A positive exponent means to multiply by a power of 10. A negative exponent means to divide. Briefly, the exponent indicates the number of 0's. in the power of 10. To go further into the meaning of an exponent, see Lessons 13 and 21 of Skill in Algebra.
How to write a number in scientific notation?
A number is written in scientific notation when there is one non-zero digit to the left of the decimal point. That number is written in scientific notation. There is one digit to the left of the decimal point -- 2 -- and it is not 0. In general, a number written in scientific notation will be multiplied by 10 raised to an "exponent.".
What does the prefix centi mean?
The prefix centi signifies the hundredth part. The prefix milli signifies the thousandth part. Relations between units of the same kind. The rule for expressing meters as kilometers, for example, or grams as centigrams, is as follows: To convert to a different metric unit of the same kind, shift the decimal.
Calculator Use
Convert a number to and from scientific notation, e notation, engineering notation, standard form, and real numbers. Enter a number or a decimal number or scientific notation and the calculator converts to scientific notation, e notation, engineering notation, and standard form formats.
How to Convert a Number to Scientific Notation
The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ | a | < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

What is scientific notation?
Scientific notation is a way to express numbers in a form that makes numbers that are too small or too large more convenient to write. It is commonly used in mathematics, engineering, and science, as it can help simplify arithmetic operations. In scientific notation, numbers are written as a base, b, referred to as the significand, ...
Is e notation the same as scientific notation?
E-notation is almost the same as scientific notation except that the "× 10" in scientific notation is replaced with just "E.". It is used in cases where the exponent cannot be conveniently displayed. It is written as: bEn.
What is engineering notation?
Engineering notation. Engineering notation is similar to scientific notation except that the exponent, n, is restricted to multiples of 3 such as: 0, 3, 6, 9, 12, -3, -6, etc. This is so that the numbers align with SI prefixes and can be read as such.
Standard Notation
Standard notation is the usual way to write numbers, with or without commas and decimals. This example calculation solves the addition problem 122500 + 3655. Click on the link and then refer to the calculator above. Note that the inputs are standard notation numbers. The answers are formatted in scientific notation and E notation.
Scientific Notation
In scientific notation a large number is converted to an equivalent decimal number between 1 and 10, multiplied by 10 raised to some power. Very small numbers are converted to an equivalent decimal number between 1 and 10, multiplied by 10 raised to some negative power.
E Notation
E notation is also known as exponential notation. E notation is the same as scientific notation where a decimal number between 1 and 10 is multiplied by 10 raised to some power. In E notation the "times 10 raised to a power" is replaced with the letter e in either uppercase or lowercase. The number after the "e" indicates how many powers of 10.
Note: Doing Math With Significant Figures
There are some cases where you would not want to auto-calculate significant figures. If your calculation involves a constant or an exact value as you might find in a formula, do not check the "auto-calculate" box.

See our Rounding Significant Figures Calculator for more information on significant figures.
What is scientific notation?
Scientific notation is a form of presenting very large numbers or very small numbers in a simpler form. As we know, the whole numbers can be extended till infinity, but we cannot write such huge numbers on a piece of paper. Also, the numbers which are present at the millions place after the decimal needed to be represented in a simpler form. Thus, it is difficult to represent a few numbers in their expanded form. Hence, we use scientific notations. Also learn, Numbers In General Form.
How to find the power of 10?
To determine the power or exponent of 10, we must follow the rule listed below: The base should be always 10. The exponent must be a non-zero integer, that means it can be either positive or negative. The absolute value of the coefficient is greater than or equal to 1 but it should be less than 10.
When do we use positive exponents for base 10?
When the scientific notation of any large numbers is expressed, then we use positive exponents for base 10. For example:#N#20000 = 2 x 10 4, where 4 is the positive exponent.
Can a coefficient be positive?
Coefficients can be positive or negative numbers including whole and decimal numbers. The mantissa carries the rest of the significant digits of the number. Let us understand how many places we need to move the decimal point after the single-digit number with the help of the below representation.
How to convert scientific notation to standard form?
To convert a number from scientific notation to standard form, we should move the decimal point (if any) to the left if the exponent of 10 is negative; otherwise, proceed to the right.
