📏 Understanding Millimeters and Decimeters

Millimeter (mm):
A millimeter is one of the smallest units in the metric system, often used for measuring tiny objects such as paper thickness, jewelry, parts of machinery, or even rainfall.
👉 1 millimeter = 0.001 meter

Decimeter (dm):
A decimeter is a medium-sized metric unit used to measure lengths or distances larger than centimeters but smaller than meters. It is commonly used in educational, scientific, and technical contexts.
👉 1 decimeter = 0.1 meter

🔢 Conversion Relationship Between Millimeters and Decimeters

The conversion is based on their relationship with the meter (SI base unit of length):
1 mm = 0.001 m
1 dm = 0.1 m

So,
1 Millimeter = 0.01 Decimeter

⚖️ Formula for Millimeter to Decimeter Conversion

The formula is simple and direct:

This means that to convert millimeters into decimeters, you just divide the millimeter value by 100.

📚 Step-by-Step Solved Examples

Convert 100 mm to dm

✅ So, 100 millimeter = 1 decimeters

Convert 250 mm to dm

✅ So, 250 millimeter = 2.5 decimeters

Convert 500 mm to dm

✅ So, 500 millimeter = 5 decimeters

Convert 1200 mm to dm

✅ So, 1200 millimeter = 12 decimeters

Convert 10,000 mm to dm

✅ So, 10,000 millimeter = 100 decimeters
