What is Bulk Modulus?
Definition
Bulk modulus measures how much a material resists being compressed. It tells us how stiff or flexible a material is when pressure is applied from all sides.
Units
Bulk modulus is measured in pressure units like GPa (gigapascals), PSI (pounds per square inch), bar, and pascal. Higher values mean stiffer materials.
Applications
Used in engineering, construction, material science, and manufacturing to choose the right materials for different jobs and conditions.
Simple Explanation
Think of bulk modulus like this: imagine you have a sponge and a steel ball. When you squeeze both with the same force, the sponge compresses easily (low bulk modulus) while the steel ball barely changes (high bulk modulus).
Materials with high bulk modulus are harder to compress and are often used where strength is important. Materials with low bulk modulus compress easily and might be used for cushioning or flexibility.

Practice Problems with Solutions
Problem 1:
Convert 50 GPa to PSI
Solution:
50 GPa = 50 ร 1,000,000,000 Pa = 50,000,000,000 Pa

Frequently Asked Questions
What is bulk modulus in simple terms?
Bulk modulus measures how hard it is to squeeze or compress a material. Think of it like the stiffness of a material when pressure is applied from all directions.
Why do we need to convert bulk modulus units?
Different countries and industries use different units. Engineers might get data in GPa but need it in PSI for their calculations, or vice versa.
Which materials have high bulk modulus?
Hard materials like diamond, steel, and tungsten have high bulk modulus. They resist compression and are very stiff.
Which materials have low bulk modulus?
Soft materials like rubber, foam, and liquids have low bulk modulus. They compress easily when pressure is applied.
How accurate is this converter?
Our converter uses precise conversion factors and provides results accurate to 8 decimal places, suitable for professional engineering calculations.
What's the difference between bulk modulus and other moduli?
Bulk modulus measures resistance to compression from all sides. Young's modulus measures stretching resistance, and shear modulus measures resistance to twisting or sliding.
