How to Calculate Gas Pressure & Volume (P1V1 = P2V2)
Calculate isothermal gas compression step-by-step:
STEP 01
Enter Initial P1 & V1
Input starting pressure P1 and volume V1.
STEP 02
Enter Target P2
Input compressed or expanded pressure P2.
STEP 03
Apply Inverse Product
Divide V2 = (P1 × V1) / P2.
STEP 04
View Final Volume V2
Get exact final volume V2 in Liters.
Key Features & Isothermal Physics
Isothermal Inverse Relation

Scuba & Piston Physics
Essential for scuba diving depth pressure and syringe/piston compression.
Physical Chemistry Guide: Boyle's Law
Boyle's Law (discovered by Robert Boyle in 1662) states that at a constant temperature, the volume of a confined ideal gas is inversely proportional to its pressure:P_1 · V_1 = P_2 · V_2

Frequently Asked Questions
?How does Boyle's Law apply to scuba diving?
As a diver ascends, ambient water pressure decreases, causing air inside lungs/BCDs to expand. Divers must continuously exhale to prevent lung overexpansion injury.
