Formula Sheet Builder — Build a Personal Equation Reference
A personal formula sheet is one of the most effective study tools for STEM subjects. The act of curating and annotating formulas forces you to understand them — not just recognise them. The free formula sheet builder on PublicSoftTools lets you save, search, and export your equations by subject.
Subjects and Example Formulas
| Subject | Example formulas |
|---|---|
| Math | Quadratic formula, area of a circle, Pythagorean theorem |
| Physics | F = ma, E = mc², V = IR, kinematic equations |
| Chemistry | PV = nRT, pH = −log[H⁺], Arrhenius equation |
| Statistics | Mean, standard deviation, z-score, binomial formula |
| Economics | Supply/demand elasticity, present value, GDP formula |
How to Use the Formula Sheet Builder
- Open the formula sheet builder.
- Enter the formula name (e.g. "Newton's Second Law") and select a subject.
- Enter the formula (e.g. F = m × a) and optional notes about variables and units.
- Click Add formula. Use the subject filter to view formulas by subject.
- Click Export to download all formulas as a text file for printing or sharing.
How to Annotate Formulas Effectively
Always list variable definitions
In the notes field, define every variable with its unit: "F = net force (N), m = mass (kg), a = acceleration (m/s²)". This prevents unit errors and makes the formula sheet useful under exam pressure when you cannot look up definitions.
Note conditions of validity
Many formulas only apply under specific conditions. Add notes like "valid only for ideal gases", "assumes constant acceleration", "at standard pressure". This prevents applying a formula in a context where it does not hold.
Add worked example values
For formulas you struggle to remember, add a quick example in the notes: "e.g. F = 5 kg × 2 m/s² = 10 N". Concrete examples anchor abstract formulas in memory more effectively than abstract definitions.
Advanced Workflows
Pre-exam review
Filter by subject the night before an exam. Read through each formula. Cover the formula and try to write it from the name alone. Use the formula sheet as a self-test, not just a reference.
Export for open-note exams
Download the exported text file and paste it into a clean document. Format and print it as a personal reference sheet permitted for open-note exams — most institutions allow custom formula sheets if provided in advance.
