Pressure, Stress, Young’s Modulus
Pressure is the ratio of force to the area over which that force is distributed. In other words, pressure is force per unit area applied in a direction perpendicular to the surface of an object.
Pressure may be measured in any unit of force divided by any unit of area. The SI unit of pressure is the pascal (Pa). One pascal is defined as one newton per square meter. A pressure of 1 Pa is small, therefore everyday pressures are often stated in kilopascals (1 kPa = 1000 Pa). The pressure in car tires can be in the range of 180 to 250 kPa.
In continuum mechanics, stress is a measure of the internal forces acting within a deformable body, which either reversibly or irreversibly changes its shape. It is a measure of the average force per unit area of a surface within the body on which internal forces act. These internal forces arise as a reaction to external forces applied to the body. These internal forces are distributed continuously within the volume of the material body, and result in deformation of the body shape. Beyond limits of material strength, this can lead to a permanent shape change or structural failure.
The dimension of stress is the same as that of pressure, and therefore the SI unit for stress is the pascal (Pa), which is equivalent to one newton per square meter (N/m²). In Imperial units, stress can be measured in pound-force per square inch, which is abbreviated as psi.
Using the Pressure, Stress, Young’s Modulus Converter
This online unit converter allows quick and accurate conversion between many units of measure, from one system to another. The Unit Conversion page provides a solution for engineers, translators, and for anyone whose activities require working with quantities measured in different units.
You can use this online converter to convert between several hundred units (including metric, British and American) in 76 categories, or several thousand pairs including acceleration, area, electrical, energy, force, length, light, mass, mass flow, density, specific volume, power, pressure, stress, temperature, time, torque, velocity, viscosity, volume and capacity, volume flow, and more.
Note: Integers (numbers without a decimal period or exponent notation) are considered accurate up to 15 digits and the maximum number of digits after the decimal point is 10.
In this calculator, E notation is used to represent numbers that are too small or too large. E notation is an alternative format of the scientific notation a · 10x. For example: 1,103,000 = 1.103 · 106 = 1.103E+6. Here E (from exponent) represents “· 10^”, that is “times ten raised to the power of”. E-notation is commonly used in calculators and by scientists, mathematicians and engineers.
- Select the unit to convert from in the left box containing the list of units.
- Select the unit to convert to in the right box containing the list of units.
- Enter the value (for example “15”) into the left From box.
- The result will appear in the Result box and in the To box.
- Alternatively, you can enter the value into the right To box and read the result of conversion in the From and Result boxes.
