Salinity Calculator

Formula

The formula to calculate the Salinity (S) is:

$S = \frac{MS}{MSW} \times 1000$

Where:

$S$ is the salinity (grams of salt per 1000 grams of seawater) (ppt)
$MS$ is the mass of the salts (grams)
$MSW$ is the mass of the salt water (grams)

Salinity Definition

Salinity is defined as the amount of salt, in mass, in a given unit of water. The water is often referred to as saltwater or seawater. If there are 5 grams of salt in 1000 grams of seawater, the salinity in parts per 1000 would be 5 ppt.

Example Calculation

Let's assume the following values:

Mass of Salts (MS) = 5 grams
Mass of Salt Water (MSW) = 1000 grams

Using the formula to calculate the Salinity (S):

$S = \frac{5}{1000} \times 1000 = 5 \, \text{ppt}$

The Salinity (S) is 5 ppt.
