5mm as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to understand units of measurement and decimals. A measurement in millimeters represents a length in the metric system. Decimals are used to express values that are not whole numbers, where a decimal point separates the whole number from the fractional part. The numbers to the left of the decimal point represent the whole number, and those to the right represent the fractional part.

Answer

 

5mm in decimals can be written as 0.005 meters. This conversion is straightforward because millimeters are a part of the metric system, where 1 meter equals 1000 millimeters.

 

Explanation

 

To convert 5mm to a decimal in meters, we use the conversion factor. Let's see the step-by-step breakdown of the process:

 

Step 1: Understand that 1 meter equals 1000 millimeters.

 

Step 2: To find the decimal representation of 5mm in meters, divide 5 by 1000.

 

Step 3: Performing the division gives us 5 ÷ 1000 = 0.005. Thus, 5mm can be expressed as 0.005 meters as a decimal. This conversion shows the relationship between millimeters and meters using the decimal system.
