Biology Calculators: Tools for Lab, Genetics & Beyond

Handy Tools for Biology Lovers and Animal Owners Alike

Whether you’re a student, a farmer, a pet parent, or just curious about how life works, biology touches your day-to-day more than you might think. From genetics and nutrition to pregnancy tracking and farming needs, the world of biology is full of useful info. And we’ve got calculators that help you figure it all out without needing a Science degree.

You’ll find tools for everything from animal gestation periods and pet health to DNA and population growth. Whether you want to know how many cattle your land can handle or how to set up a Punnett square, we’ve built tools to make it easier.

Keeping Pets Healthy and Happy

Caring for a cat or dog means more than feeding and walking. Our pet calculators help with nutrition, aging, pregnancy, and even medical concerns.

• Dog Food Calculator and Cat Calorie Calculator take the guesswork out of feeding. Just plug in weight, activity, and age to get a daily calorie range.
• Dog Age Calculator and Cat Age Calculator help you figure out how old your pet is in “human years.” It’s fun and also useful for health planning.
• If your dog or cat is pregnant, the Dog Pregnancy Calculator or Cat Pregnancy Calculator can estimate when the litter is due.
• The Dog Heat Cycle Calculator tracks your pup’s fertility cycle, especially helpful for breeders.
• Dog Quality of Life Calculator and Cat Quality of Life Calculator guide you through tough decisions with empathy and clarity.
• Worried about treats gone wrong? The Dog Chocolate Toxicity Calculator and Cat Chocolate Toxicity Calculator estimate the risk based on the amount and type of chocolate eaten.
• If you’re going the natural route, the Raw Dog Food Calculator and Dog Nutrition Calculator are there to help you plan balanced raw meals.

Farm Life Made Easier

If you manage livestock, you know how helpful it is to plan ahead. Our farming tools are built to support your herd and your harvest.

• Expecting a new arrival? Use the Goat Gestation Calculator, Sheep Gestation Calculator, Cow Gestation Calculator, Horse Gestation Calculator, or Mare Gestation Calculator to estimate due dates and prep in time.
• Wondering how many animals your land can support? The Cattle Per Acre Calculator makes it easy to plan grazing areas.
• Trying to predict your crop yield? The Corn Yield Calculator gives a quick estimate based on row and ear counts.
• For lawn care and soil prep, the Soil Calculator, Sod Calculator, Lawn Mowing Cost Calculator, and Compost Calculator help you figure out how much you need and how much it’ll cost.

Understanding Genetics and DNA

Whether you’re brushing up on homework or studying your family tree, these tools help explain how traits and molecules work.

• The Punnett Square Calculator helps predict the chances of certain traits in offspring.
• The Allele Frequency Calculator shows how common certain gene variants are in a population.
• Blood Type Calculator and Blood Type Inheritance Calculator help you work out possible blood types in a family based on parents or children.
• For molecular biology tasks, the DNA Melting Temperature Calculator, Annealing Temperature Calculator, Ligation Calculator, and Protein Molecular Weight Calculator are helpful during lab work or class assignments.
• Need to calculate protein amounts? Try the Protein Concentration Calculator for accurate values based on absorbance and extinction coefficient.

Keeping an Eye on Populations and the Planet

Big-picture biology can also be practical. If you’re working on an environmental science project or keeping tabs on wildlife or community growth, there’s a tool for that too.

• The Population Growth Rate Calculator works out how fast a group is growing over time.
• The Doubling Time Calculator helps predict when a population will double.
• The Ecological Footprint Calculator helps you estimate how much land and water it takes to support your lifestyle—useful for thinking about sustainability.

Planting, Planning, and Spacing Things Out

You don’t have to be a farmer to need help planning your outdoor space. Whether you're setting up a backyard orchard or expanding your garden, we’ve got tools that fit.

• The Tree Spacing Calculator makes sure you plant trees with enough room to grow, which helps prevent disease and overcrowding.
• Planning your lawn or garden beds? The Sod Calculator and Soil Calculator help you get the right amount of materials the first time.
• Use the Lawn Mowing Cost Calculator to budget time and money for yard upkeep.
• Composting? The Compost Calculator helps you figure out how much green and brown matter you need to break down scraps into rich soil.

Whatever you're working on—from raising puppies to calculating protein size—try one of our biology calculators and see how much easier life can be.
