0.005 g in scientific notation is 5.0 × 10-3 g.
To convert 0.005 grams into scientific notation, you move the decimal point so that only one non-zero digit remains to the left of the decimal. Here, 0.005 becomes 5.0 multiplied by 10 raised to the power of -3, representing the three places the decimal was shifted to the right.

Conversion Formula
Scientific notation expresses numbers as a product of a number between 1 and 10 and a power of 10. To convert grams (g) into scientific notation, find the position of the decimal point and shift it until only one non-zero digit remains to its left.
The general formula is:
Scientific Notation = (Original number) ÷ 10n × 10n
Where n is how many places the decimal point moves to make the number between 1 and 10.
For example, converting 0.005 g:
- Move decimal 3 places right: 0.005 → 5.0
- Because you moved right, n = -3
- Scientific notation: 5.0 × 10-3
Conversion Example
- Convert 1200 g:
- Move decimal 3 places left: 1200 → 1.2
- n = 3 (positive because decimal moves left)
- Scientific notation: 1.2 × 103
- Convert 0.00045 g:
- Move decimal 4 places right: 0.00045 → 4.5
- n = -4
- Scientific notation: 4.5 × 10-4
- Convert 75 g:
- Move decimal 1 place left: 75 → 7.5
- n = 1
- Scientific notation: 7.5 × 101
- Convert 0.3 g:
- Move decimal 1 place right: 0.3 → 3.0
- n = -1
- Scientific notation: 3.0 × 10-1

Conversion Definitions
g (gram): The gram is a metric unit of mass equal to one-thousandth of a kilogram. It’s widely used to measure small masses in science, cooking, and commerce. The gram allows precise measurement of materials, substances, or ingredients in everyday and technical contexts.
Scientific notation: A method of writing numbers as a product of a decimal number between 1 and 10 and a power of ten. It simplifies handling extremely large or small numbers by expressing them compactly with exponents, making calculations and comparisons easier in science and engineering.
Conversion FAQs
Why is scientific notation useful for converting grams?
Scientific notation makes it easier to work with very small or large gram values. Instead of writing many zeros, it expresses numbers compactly, saving space and reducing errors in reading or calculations, especially in scientific experiments or engineering measurements.
How do I know how many decimal places to move when converting?
The decimal point moves until only one non-zero digit remains to the left. The number of places moved determines the exponent on 10. If you move right, the exponent is negative; if left, it’s positive. Counting the moves correctly is key to accurate conversion.
Can negative gram values be converted to scientific notation?
Yes, negative values keep the negative sign and convert the absolute value to scientific notation. For example, -0.005 g becomes -5.0 × 10-3 g. The sign remains outside the scientific format to indicate direction or deficit in quantity.
What happens if the value is zero?
Zero in grams is zero in scientific notation as well. It cannot be expressed with a power of ten since no exponent can represent zero, so it stays simply as 0.
Is the precision affected when converting to scientific notation?
Precision depends on how many decimal places you keep in the coefficient part of scientific notation. Rounding too much may lose detail. It’s important to keep enough digits for the task, especially in scientific contexts where accuracy is critical.
