Grams to Moles Chemistry
Unit Factors & 75+ Calculators
Free · In‑App Purchases · Designed for iPad
Unit factors with cancelled units crossed out, plus 75+ chemistry and physics calculators that solve for any variable. On iPhone, iPad and Mac. Try it free for a month.
Grams to Moles Chemistry shows you every step of a unit conversion, not just the answer.
Version 2.0 is a complete rebuild: a new Unit Factors converter, more than 75 chemistry and physics calculators that solve for any variable, curve fitting for your lab data, and the molar mass calculator and periodic table tools students have used for years.
UNIT FACTORS, SHOWN STEP BY STEP
• Convert grams to moles, moles to particles, liters to cubic feet, g/mL to kg/m³ and much more.
• Every unit factor in the chain is written out, and each unit is crossed out in red as it cancels, so you can see why the answer is right.
• Type any chemical formula, including hydrates and complex ions such as CuSO4·5H2O or K4[Fe(CN)6], and the molar mass is worked out for you.
• Categories include mass, volume, length, pressure, energy, power, time, density, speed, flow rate, temperature, concentration (mol/L, g/L, mg/L, g/ft³, g/in³ and more), ppm ↔ mass percent and ppmv ↔ volume percent.
CALCULATIONS: SOLVE FOR ANY VARIABLE
More than 75 equations in 12 topics. Fill in what you know and solve for whichever variable is missing:
• Gas laws
• Solutions
• pH and acids/bases
• Buffers
• Electrochemistry
• Thermodynamics and Gibbs energy
• Energy and heat
• Electricity and circuits
• Electricity and magnetism
• Classical mechanics
• Quantum mechanics
• Statistical mechanics
Also included: heating and cooling curves (q = m·c·ΔT and q = n·ΔH for each step, with the curve plotted), resistors and capacitors in series and parallel, and a table of physical constants.
CURVE FITTING
Enter your lab data and fit it to 10 models: linear, quadratic, exponential, exponential with offset, power law, logarithmic, Michaelis–Menten, logistic, Gaussian peak and Arrhenius. You get the fitted parameters and a graph of the fit.
MOLAR MASS AND THE PERIODIC TABLE
• Molar mass calculator for any chemical formula
• Scrolling, zooming periodic table with element details
• Element look-up by symbol or by atomic number
MADE FOR STUDENTS AND TEACHERS
Grams to Moles Chemistry is for high-school and college chemistry and physics students, their teachers, and anyone who works with units. The unit-factor method it teaches works for every conversion, not just chemistry.
