## What is the Formula to convert Millimeters to Decimeters?

The formula to convert given length from Millimeters to Decimeters is:

Length_{(Decimeters)} = Length_{(Millimeters)} × 0.01

Substitute the given value of length in millimeters, i.e., Length_{(Millimeters)} in the above formula and simplify the right-hand side value. The resulting value is the length in decimeters, i.e., Length_{(Decimeters)}.

## Calculation

## Examples

### Consider that a premium camera lens has a focal length of 85 millimeters.

Convert this focal length from millimeters to Decimeters.

#### Answer:

**Given:**

The length in millimeters is:

Length_{(Millimeters)} = 85

**Formula:**

The formula to convert length from millimeters to decimeters is:

Length_{(Decimeters)} = Length_{(Millimeters)} × 0.01

**Substitution:**

Substitute given weight **Length _{(Millimeters)} = 85** in the above formula.

Length_{(Decimeters)} = 85 × 0.01

Length_{(Decimeters)} = 0.85

**Final Answer:**

Therefore, **85 mm** is equal to **0.85 dm**.

The length is **0.85 dm**, in decimeters.

### Consider that a luxury watch's thickness is 12 millimeters.

Convert this thickness from millimeters to Decimeters.

#### Answer:

**Given:**

The length in millimeters is:

Length_{(Millimeters)} = 12

**Formula:**

The formula to convert length from millimeters to decimeters is:

Length_{(Decimeters)} = Length_{(Millimeters)} × 0.01

**Substitution:**

Substitute given weight **Length _{(Millimeters)} = 12** in the above formula.

Length_{(Decimeters)} = 12 × 0.01

Length_{(Decimeters)} = 0.12

**Final Answer:**

Therefore, **12 mm** is equal to **0.12 dm**.

The length is **0.12 dm**, in decimeters.

## Millimeters

A millimeter (mm) is a unit of length in the International System of Units (SI). One millimeter is equivalent to 0.001 meters or approximately 0.03937 inches.

The millimeter is defined as one-thousandth of a meter, making it a precise measurement for small distances.

Millimeters are used worldwide to measure length and distance in various fields, including engineering, manufacturing, and everyday life. Many industries, especially those requiring high precision, have adopted the millimeter as a standard unit of measurement for small lengths.

## Decimeters

A decimeter (dm) is a unit of length in the International System of Units (SI). One decimeter is equivalent to 0.1 meters or approximately 3.937 inches.

The decimeter is defined as one-tenth of a meter, making it a convenient measurement for intermediate lengths.

Decimeters are used worldwide to measure length and distance in various fields, including science, engineering, and everyday life. They provide a useful scale for measurements that are larger than centimeters but smaller than meters, and are commonly used in educational settings and certain industries.

## Frequently Asked Questions (FAQs)

### 1. How do I convert millimeters to decimeters?

To convert millimeters to decimeters, divide the number of millimeters by 100, since there are 100 millimeters in a decimeter. For example, 250 millimeters divided by 100 equals 2.5 decimeters.

### 2. What is the formula for converting millimeters to decimeters?

The formula is: \( \text{decimeters} = \dfrac{\text{millimeters}}{100} \).

### 3. How many decimeters are in a millimeter?

There are 0.01 decimeters in 1 millimeter.

### 4. Is 100 millimeters equal to 1 decimeter?

Yes, 100 millimeters is equal to exactly 1 decimeter.

### 5. How do I convert decimeters to millimeters?

To convert decimeters to millimeters, multiply the number of decimeters by 100. For example, 5 decimeters multiplied by 100 equals 500 millimeters.

### 6. Why do we divide by 100 to convert millimeters to decimeters?

Because there are 100 millimeters in one decimeter, dividing by 100 converts millimeters to decimeters.

### 7. How many decimeters are there in 850 millimeters?

850 millimeters divided by 100 equals 8.5 decimeters.
