Standard, scientific, mole, energy, stoichiometry, and equation balancing calculators.
Use the calculators above, then scroll down for formulas, examples, chemistry help, and calculator explanations.
Keyboard works: numbers, operators, Enter, Backspace, and Escape. Use Convert to change decimals into fractions or π/radian form.
Scientific mode supports DEG/RAD, trig, inverse trig, powers, roots, log, ln, π, e, and Ans. Convert cycles Decimal → Fraction → π/Radian → Decimal.
Formula: moles = grams ÷ molar mass. Press Enter to calculate.
1 calorie = 4.184 joules. 1 food Calorie = 1 kilocalorie = 1000 calories.
Flow: grams given → moles given → mole ratio → grams wanted.
Use -> between reactants and products. Example: CH4 + O2 -> CO2 + H2O
MultiCalX is a multi-calculator hub built for quick math, science, chemistry, and conversion work. Choose a calculator tab, enter the values needed for that tool, and use the result area to check the final answer.
The standard and scientific calculators are useful for everyday arithmetic, algebra, trigonometry, powers, roots, logarithms, and angle-based calculations. The chemistry tools help with mole conversions, energy conversions, stoichiometry, and chemical equation balancing.
Use this for addition, subtraction, multiplication, division, percentages, parentheses, and quick conversions.
Use this for trigonometry, inverse trigonometry, square roots, exponents, logarithms, π, e, and degree/radian mode.
Convert grams into moles when you know the molar mass of the substance.
moles = grams ÷ molar mass
Convert between calories, food Calories, joules, and kilojoules.
1 cal = 4.184 J
Use mass, molar mass, and mole ratios to estimate the amount of product or reactant needed.
Enter a chemical equation and balance reactants and products using whole-number coefficients.
Many calculator problems are easier to understand when the formula is visible before the numbers are entered. These are the core formulas used by the chemistry and energy tools on this page.
Use DEG mode when working with degree-based angles, such as many classroom trigonometry problems. Use RAD mode when working with radians, unit circle values, calculus, or formulas that naturally use π.
The Convert button helps cycle a decimal result into a fraction or a π/radian-style form when possible. This is useful for checking answers that need to be entered as fractions or exact angle values.
Chemistry calculations usually depend on keeping units organized. Start by writing down the known value, identify the conversion factor, and then convert step by step.
Yes. MultiCalX is a free calculator platform for everyday math, scientific calculations, and chemistry help.
Yes. The scientific calculator includes a DEG/RAD toggle so angle calculations can match the type of problem being solved.
Yes. The mole, stoichiometry, energy, and equation balancing tools are designed to support learning and checking work. Always verify your final answer with the method required by your class or instructor.
Chemical formulas are case-sensitive. For example, CO means carbon monoxide, while Co means cobalt. Correct capitalization helps the balancer identify elements properly.
Yes. The layout is responsive and works on desktops, tablets, and phones.
