Understanding Pressure Units
To convert pounds per square inch (psi) to kilopascals (kPa), it’s essential to understand the relationship between these units.
Pressure Conversion Basics
- **1 psi** is equivalent to **6.89476 kPa**.
- Therefore, to convert psi to kPa, you multiply the psi value by 6.89476.
Conversion Factor Explanation
- To find the conversion factor from psi to kPa, you take the reciprocal of 6.89476:
- \[ \text{Conversion Factor} = \frac{1}{6.89476} \approx 0.145 \]
However, the options provided include a factor that seems to reflect the reciprocal of the conversion from kPa to psi instead.
Analyzing the Options
- **Option A: 0.0069** - This option does not accurately represent the conversion factor for psi to kPa, as it is significantly lower than the correct reciprocal.
- **Option D: 6.8948** - This is the correct conversion for psi to kPa.
Conclusion
The correct answer should be **Option D (6.8948)**, as this represents how many kilopascals are in one pound per square inch.
To summarize:
- **1 psi = 6.89476 kPa**, hence **to convert psi to kPa, multiply by 6.89476**.
- The provided option **A (0.0069)** is incorrect for this conversion.
Always ensure to verify conversion factors for accurate results in calculations!

Understanding the Conversion Factor
To convert square meters to square feet, it’s essential to understand the basic relationship between these two units of area.
Square Meters and Square Feet
- A square meter (m²) is a metric unit of area, while a square foot (ft²) is an imperial unit.
- The conversion factor between meters and feet is crucial to derive the conversion between square meters and square feet.
Conversion Factor Between Meters and Feet
- 1 meter is approximately equal to 3.2808 feet.
- Therefore, when converting area, you need to square the linear conversion factor since area is measured in two dimensions.
Calculating the Conversion from Square Meters to Square Feet
- To convert square meters to square feet, you square the conversion factor:
- (3.2808 feet)² = 10.7639 square feet per square meter.
- This means that for every 1 square meter, you have approximately 10.7639 square feet.
Conclusion
- The correct conversion factor to convert square meters to square feet is not simply 3.2808 but rather involves squaring it to achieve the area conversion.
- Therefore, the answer to the question is option 'D', which highlights the importance of understanding both the linear and area conversions when dealing with different measurement systems.
By knowing this conversion, you can accurately translate measurements between metric and imperial systems, which is particularly useful in fields like construction, real estate, and various scientific applications.
