Biology
Biology on this site splits into two very different audiences: pet owners tracking a dog or cat's dosage, weight, or breeding timeline, and lab or field scientists working through genetics crosses, cell culture math, or livestock feed ratios. The subcategories below reflect that split, from Dog and Cat Calculators built for everyday pet care to Bio Laboratory Calculators aimed at cellular and microbiology work.
Categories in Biology
Animal Pregnancy
Ten species-specific gestation calculators live here, spanning a roughly nine-week dog pregnancy to the roughly eleven-month gestation of a mare. Each uses the typical range published for that species rather than a single averaged number, since actual timing varies by breed and individual animal.
Bio Laboratory Calculators
These eight tools handle the recurring math of a wet lab: working out ligation insert-to-vector ratios, DNA concentration from absorbance readings, primer annealing temperatures, or how many population doublings a culture has gone through between two cell counts. Built for students and researchers who already know the underlying protocol and just need the arithmetic done precisely.
Livestock
Farm-scale math lives here rather than backyard pet care: feed conversion efficiency, grain bin storage capacity, stocking rate, fence cost estimation, and herd mortality tracking, built for smallholders and working farms.
Genetics
Punnett square tools for predicting cross outcomes from monohybrid through trihybrid crosses, allele frequency calculations, and qPCR efficiency and DNA copy number tools for the molecular side: classical and molecular genetics built for coursework and lab use alike.
Cat Calculators
This subcategory mirrors the dog calculators for cat owners: BMI and calorie needs, growth projections, medication dosages like cephalexin and metronidazole, and a chocolate toxicity checker. As with the dog dosage tools, these are reference calculators only, not a replacement for veterinary guidance.
Dog Calculators
This is the largest single subcategory on the site: 22 calculators covering everything a dog owner needs, from BMI and life expectancy to medication dosages like tramadol and cephalexin, plus toxicity checks for foods dogs shouldn't eat like chocolate, onions, and raisins. Dosage calculators here are for reference only and never a substitute for your veterinarian's actual prescription.
