Megarayls to pascal-seconds per meter

Type a value in MRayl to get it in Pa·s/m instantly.

1,500,000Pa·s/m

That's 1.01× as hard as water, while muscle is 1.13× higher. At a boundary with water, about 0% of the sound reflects.

What it means

How much reflects?

Reflection figures are for a boundary with water, at normal incidence. Soft tissue is close enough to water to use the same numbers.

The math

How to convert MRayl to Pa·s/m

To convert megarayls to pascal-seconds per meter, multiply by 1,000,000.

Example: 1.5 MRayl × 1,000,000 = 1,500,000 Pa·s/m.

In the other direction, 1 Pa·s/m = 1×10⁻⁶ MRayl.
