- [BMR Calculator](https://biology.studentgpacalculator.com/bmr/): Estimate your Basal Metabolic Rate using the Mifflin-St Jeor equation, which research shows is the most accurate of the common BMR formulas.
- [Population Growth Calculator](https://biology.studentgpacalculator.com/population-growth/): Model exponential and logistic population growth. Project how a population changes over multiple generations using standard ecological growth equations.
- [Dilution Calculator](https://biology.studentgpacalculator.com/dilution/): Calculate serial dilutions.
- [Hardy-Weinberg Equilibrium Calculator](https://biology.studentgpacalculator.com/hardy-weinberg/): Test whether a population is in Hardy-Weinberg equilibrium.
- [DNA Translation Tool](https://biology.studentgpacalculator.com/dna-translation/): Paste a DNA or mRNA sequence and get the amino acid sequence. Supports all three reading frames and handles both DNA (T) and mRNA (U) input.
- [Chi-Square Test Calculator](https://biology.studentgpacalculator.com/chi-square/): Run a chi-square goodness-of-fit test. Enter observed and expected counts for each category to determine whether the difference is statistically significant.
- [Water Potential Calculator](https://biology.studentgpacalculator.com/water-potential/): Calculate water potential from solute potential and pressure potential. Enter molarity to derive solute potential automatically using the van 't Hoff equation.
- [Molarity Calculator](https://biology.studentgpacalculator.com/molarity/): Calculate molarity (mol/L), moles of solute, grams needed, or volume of solution. Works for any chemical solution.
- [BMI Calculator](https://biology.studentgpacalculator.com/bmi/): Calculate Body Mass Index from your height and weight. Supports both metric (cm/kg) and imperial (ft/in/lb) units.
