Understanding the Problem

When working with measurements, it's essential to understand the relationships between different units. In this article, we'll focus on converting units of force, specifically from Newtons per centimeter (N/cm) to Newtons per millimeter (N/mm). The given equation is:

(−7.8×105Ncm)⋅□=?Nmm\left(-7.8 \times 10^5 \frac{N}{cm}\right) \cdot \square = ? \frac{N}{mm}

The Importance of Unit Conversion

Unit conversion is a crucial aspect of scientific and mathematical calculations. It allows us to express quantities in different units, making it easier to compare and analyze data. In this case, we need to convert the given force from N/cm to N/mm.

The Role of the Missing Value

The missing value, represented by the square, is a crucial component of the equation. It will determine the final result of the conversion. To find the missing value, we need to understand the relationship between centimeters and millimeters.

Relationship Between Centimeters and Millimeters

There are 10 millimeters in 1 centimeter. This means that to convert a measurement from centimeters to millimeters, we need to multiply the value by 10.

Applying the Conversion Factor

To convert the given force from N/cm to N/mm, we need to multiply the value by 10. This is because there are 10 millimeters in 1 centimeter.

Calculating the Missing Value

Now that we understand the relationship between centimeters and millimeters, we can calculate the missing value.

(−7.8×105Ncm)⋅10=?Nmm\left(-7.8 \times 10^5 \frac{N}{cm}\right) \cdot 10 = ? \frac{N}{mm}

Simplifying the Equation

To simplify the equation, we can multiply the values.

−7.8×105⋅10=−7.8×106Nmm-7.8 \times 10^5 \cdot 10 = -7.8 \times 10^6 \frac{N}{mm}

The Final Result

The final result of the conversion is:

−7.8×106Nmm-7.8 \times 10^6 \frac{N}{mm}
