How To Calculate Proportionality Constant . 24 = k (3) k = 24 ÷ 3 = 8. We know that y varies proportionally with x. PPT Constant of Proportionality! PowerPoint Presentation, free from www.slideserve.com Generally, the constant proportionality calculator plays an important role to find the constant of proportionality in the physics, mathematics, and engineering fields. 30 = k (3) 10 = k. You see 1/2 is equal to k here, pi is equal to k right over there.
