Science Tools
Scientific calculators for chemistry, physics, and research. Calculate molecular weights, determine pH levels, and perform scientific computations. Essential tools for students, researchers, and professionals in STEM fields.
Molecular Weight Calculator
Calculate the molecular weight of chemical compounds from their formulas. Supports complex formulas with parentheses, subscripts, and multiple elements.
pH Calculator
Calculate pH, pOH, H+ concentration, and OH- concentration. Convert between pH and hydrogen ion concentration with automatic classification of acidic, basic, or neutral solutions.
Solution Dilution Calculator
Calculate solution dilutions using C1V1=C2V2. Solve for stock concentration, stock volume, final concentration, or final volume with unit-aware inputs and dilution factor.
Density Calculator
Calculate density, mass, or volume using the density formula. Supports multiple units including kg/m³, g/cm³, g/mL, lb/ft³, and more. Perfect for physics, chemistry, and engineering calculations.
