1 mm as a Decimal

Professor Greenline Explaining Math Concepts

This is a simple question on converting units to decimals. First, we need to understand the relationship between millimeters and meters. Millimeters are a sub-unit of meters, where 1 meter is equivalent to 1000 millimeters. A decimal is used to represent a fractional part of a whole number, using a decimal point to separate the whole number from its fractional component. The numbers to the left of the decimal point represent whole units, while those to the right represent fractional parts.

Answer

1 mm in decimal form can be written as 0.001 m.

Step 2: To convert millimeters to meters, divide the number of millimeters by 1000.

 

Step 3: For 1 mm, the calculation is 1 ÷ 1000 = 0.001. Step 4:

 

Therefore, 1 mm as a decimal in meters is 0.001.
