## What is the Formula to convert Square Millimeters to Square Kilometers?

The formula to convert given area from Square Millimeters to Square Kilometers is:

Area_{(Square Kilometers)} = Area_{(Square Millimeters)} × 1e-12

Substitute the given value of area in square millimeters, i.e., Area_{(Square Millimeters)} in the above formula and simplify the right-hand side value. The resulting value is the area in square kilometers, i.e., Area_{(Square Kilometers)}.

## Calculation

## Examples

### Consider that a microchip has a surface area of 500 square millimeters.

Convert this area from square millimeters to Square Kilometers.

#### Answer:

**Given:**

The area in square millimeters is:

Area_{(Square Millimeters)} = 500

**Formula:**

The formula to convert area from square millimeters to square kilometers is:

Area_{(Square Kilometers)} = Area_{(Square Millimeters)} × 1e-12

**Substitution:**

Substitute given weight **Area _{(Square Millimeters)} = 500** in the above formula.

Area_{(Square Kilometers)} = 500 × 1e-12

Area_{(Square Kilometers)} = 5e-10

**Final Answer:**

Therefore, **500 mm ^{2}** is equal to

**5e-10 km**.

^{2}The area is **5e-10 km ^{2}**, in square kilometers.

### Consider that a small screw head covers 100 square millimeters.

Convert this area from square millimeters to Square Kilometers.

#### Answer:

**Given:**

The area in square millimeters is:

Area_{(Square Millimeters)} = 100

**Formula:**

The formula to convert area from square millimeters to square kilometers is:

Area_{(Square Kilometers)} = Area_{(Square Millimeters)} × 1e-12

**Substitution:**

Substitute given weight **Area _{(Square Millimeters)} = 100** in the above formula.

Area_{(Square Kilometers)} = 100 × 1e-12

Area_{(Square Kilometers)} = 1e-10

**Final Answer:**

Therefore, **100 mm ^{2}** is equal to

**1e-10 km**.

^{2}The area is **1e-10 km ^{2}**, in square kilometers.

## Square Millimeters

A square millimeter (mm^{2}) is a unit of area measurement equal to the area of a square with sides that are one millimeter in length. This tiny unit of area is often used in precision engineering, electronics, and materials science, where very small surface areas need to be measured accurately. Square millimeters are essential for detailing the dimensions of microchips, small mechanical parts, or any other objects where precision is crucial.

## Square Kilometers

A square kilometer (km^{2}) is a unit of area measurement equal to one million square meters or the area of a square with sides one kilometer long. It is commonly used to measure large areas such as cities, regions, and natural landscapes. Square kilometers are crucial in geography, urban planning, and environmental studies, helping to quantify and compare vast tracts of land or water, such as forests, lakes, and entire countries.
