Frequently Asked Questions

How much is 360 pounds per square inch in megapascals?

360 pounds per square inch is about 2.482113 megapascals.

How many megapascals is 1 pound per square inch?

1 pound per square inch is about 0.006895 megapascals.

How many pounds per square inch is 1 megapascal?

1 megapascal is about 145.037738 pounds per square inch.

What is the difference between pounds per square inch and megapascals?

Both measure pressure, but they are commonly used in different contexts. Pounds per square inch are often used in engineering and tire pressure, especially in US contexts. Megapascals are used for high pressures (materials, hydraulics, and engineering).

Where are pounds per square inch and megapascals used?

In practice: Pounds per square inch are often used in engineering and tire pressure, especially in US contexts. Megapascals are used for high pressures (materials, hydraulics, and engineering).

Why does 1 pound per square inch equal 0.006895 megapascals?

Because pressure units are defined with a fixed relationship (often relative to the pascal). To convert, multiply by that factor.
