What is the measure calculator?

What is a Measurement Calculator? A 'Measurement Calculator' is a free online tool that helps in converting one capacity measurement unit into another. In this calculator, you can select a measuring unit, and the unit in which you want it to convert and its equivalent will be displayed within a few seconds.

How do I find a missing angle of a triangle?

a / sin(α) = b / sin(β) so β = arcsin[b * sin(α) / a] As you know, the sum of angles in a triangle is equal to 180°. From this theorem we can find the missing angle: γ = 180°- α - β
