Species-Specific Drug Dosing
Calculate animal weight-based dosages, target mg requirements, and liquid volumes across different species: dogs, cats, horses, cattle, and rabbits.
Karat purity (Karat ↔ Fineness ↔ % gold)
Convert gold purity levels between Karat values, parts-per-thousand millesimal fineness, and pure gold percentage.
Pattern scaling — original size ↔ scaled dimensions
Scale sewing and cutting patterns up or down uniformly. Convert dimensions between source and target sizes.
Ballistic coefficient ↔ drag — projectile performance
Calculate bullet Sectional Density (SD) and Ballistic Coefficient (BC) using projectile weight, caliber, and form factor.
Crease pattern scale — diagram size ↔ actual paper needed
Scale geometric origami crease patterns and tessellations to starting square sheet sizes.
RESEARCH Utilities
Choose a specialized option to begin instant real-time conversion.
Effect size — Cohen's d ↔ r ↔ odds ratio
Convert between various effect size measures like Cohen's d, Pearson correlation r, and Odds Ratio for scientific research interpretation.
Percentile ↔ z-score ↔ standard deviation
Determine z-scores, percentiles, standard deviation steps, and probability density for standard normal distribution curves.
Likert scale ↔ numerical score
Convert Likert scale responses (e.g., 3-point, 5-point, 7-point, 10-point) into standardized numerical indices for survey research analytics.
Sample size calculator — confidence level ↔ margin of error
Determine required sample sizes for research surveys or experiments based on population size, confidence levels, and target margin of error.
IQ score ↔ percentile rank
Map IQ scores (with standard deviations 15 or 16) to cognitive percentile ranks, rarity indices, and standard intelligence brackets.
