Science Calculators

Science Calculators - Physics and Chemistry at Your Fingertips

Science calculators translate theoretical laws into practical numbers. From Newton’s second law to Ohm’s law, from solution molarity to pH - these calculators are built for students, teachers, and working scientists who need fast, formula-accurate results. Every page shows the governing equation, defines all variables with SI units, and walks through a worked example.

Two Subcategories Covering Core Sciences

Physics Calculators

The Force Calculator applies F = ma - enter any two of force, mass, and acceleration to find the third. The Kinematics Calculator solves all five SUVAT equations simultaneously from any three known variables, handling deceleration and free-fall. The Ohm’s Law Calculator covers all four modes: V, I, R, and power (P = IV = I²R = V²/R). The Projectile Motion Calculator returns range, max height, and time of flight for any launch angle and speed. The Work Energy Power Calculator covers W = Fd·cosθ, KE = ½mv², PE = mgh, and P = W/t.

Chemistry Calculators

The Molarity Calculator works in three modes - find molarity, find mass of solute, or find volume - and includes a dilution mode using M₁V₁ = M₂V₂. The Molecular Weight Calculator parses any chemical formula including parentheses (Ca(OH)₂, Al₂(SO₄)₃) and returns g/mol plus elemental composition percentages. The pH Calculator converts between [H⁺] concentration and pH in both directions, and also shows pOH using the relationship pH + pOH = 14 at 25°C.

Who These Calculators Are For

Students from Classes 9–12 and JEE/NEET aspirants will find all curriculum-relevant physics and chemistry calculations covered. Undergraduate science students can use them for lab calculations and problem-set verification. Laboratory professionals rely on the Molarity and pH calculators for rapid solution preparation checks.
