Centimeters (cm) and millimeters (mm) are both units of length in the metric system, which is part of the International System of Units (SI).
So, how do you convert 1.5 cm into mm? It’s actually pretty easy. The conversion factor is: 1 cm = 10 mm.
Understanding centimeters and millimeters
Both centimeters and millimeters are units of length in the metric system.
- A centimeter (cm) is equal to one-hundredth of a meter (1 cm = 0.01 m).
- A millimeter (mm) is equal to one-thousandth of a meter (1 mm = 0.001 m).
Ten millimeters make up one centimeter.
Understanding the relationship between centimeters and millimeters can help you make accurate measurements in a variety of fields. Having a good grasp of the relationship can also help you convert back and forth between the two units.
How to convert 1.5 cm to mm
The formula to convert centimeters to millimeters is:
Millimeters = Centimeters 10
This works because 1 cm is always equal to 10 mm. So, to convert 1.5 cm to mm, you just multiply 1.5 by 10:
1.5 cm 10 = 15 mm
This means that 1.5 cm is the same as 15 mm.
How to convert 1.5 cm to mm
Here’s how to do it:
- Figure out the number of centimeters you want to convert. In this case, it’s 1.5 cm.
- Multiply that number by 10 (because there are 10 millimeters in every centimeter): 1.5 10
- Do the math: 15
- Add the units: 1.5 cm = 15 mm
Of course, you can always use an online conversion tool to do this for you.
Why does this matter?
Converting centimeters to millimeters comes in handy in all sorts of situations, from technical drawings and construction to tailoring and everyday measurements.
In science, millimeters are often the preferred unit.
Here’s another quick example: 2.5 cm is equal to 25 mm. (2.5 cm x 10 = 25 mm)
In Conclusion
To recap: 1.5 cm is the same as 15 mm. To make the conversion from centimeters to millimeters, you simply multiply by 10.
Understanding how to convert between units of measurement is important for precision in all kinds of everyday tasks.
