API Gravity Solution

Follow our step by step solution on how to calculate API Gravity?

FIRST Step Consider the formula

°API = (\frac{141.5}{SG}) - 131.5

Next Step Substitute values of Variables

∴

°API = (\frac{141.5}{0.82}) - 131.5

Next Step Prepare to Evaluate

∴

°API = (\frac{141.5}{0.82}) - 131.5

Next Step Evaluate

∴

°API = 41.0609756097561

LAST Step Rounding Answer

∴

°API = 41.061
