Calculate creatine loading or maintenance from body weight, serving split, label units, health context, and container supply checks.

Calculate FFMI from weight, height, and body-fat or lean-mass readings, with normalized comparison bands, sensitivity checks, and goals.

Turn pediatric visit rows into percentiles, height-velocity checks, BMI flags, trend charts, and follow-up cues for growth review.

Review a child's height, weight, or BMI percentile path across visits, with WHO/CDC context, band-crossing alerts, charts, and follow-up cues.

Review child growth visit rows in your browser for percentile drift, corrected-age routing, height velocity, adiposity alerts, and family-height triage.

Calculate child growth velocity from height or weight visit rows, compare each interval with age-stage bands, and flag spacing, streak, and drift concerns.

Check a child's growth z-score from height, weight, or BMI with WHO/CDC chart selection, percentile context, and preterm age correction.

Check a child's height-for-age percentile from age, sex, and length or stature, with z-score, WHO/CDC comparison, and screen margins.

Estimate adult ideal weight from Devine, Hamwi, Robinson, and Miller formulas, then compare the result with a BMI-based healthy-weight corridor.

Plan an intermittent fasting schedule from your first meal time, then check safety ceilings, weekend shifts, hydration cues, and rhythm charts.

Calculate lean body mass from height, weight, sex, and optional body-fat checks, with formula spread, FFMI, and warning cues for trend checks.

Calculate daily calorie and macro targets from body metrics, activity, goal pace, BMR formula, protein floor, and meal split warnings.

Estimate a child's mid-parental target height from biological parent heights, compare formula methods, and read the expected family band.

Estimate one-rep max from a completed set, compare seven formulas, and turn the result into rounded training loads and confidence cues.

Compare pregnancy weight gain with BMI-based singleton or twin ranges, week-to-date bands, and clinician-review warnings for unusual trends.

Estimate projected adult height from child height, age, sex, and parent heights with range, percentile, and family-band checks.

Plan daily protein grams from body weight, goal, training load, diet pattern, meal count, current intake, calories, and health cautions.

Convert shoe sizes from foot length or regional labels, compare US, UK, EU, JP, CN, KR, MX, and BR sizes, and flag fit or unit warnings.

Calculate active calories from steps, body weight, step length, pace, and terrain, then plan target steps with assumptions and ranges.

Plan a week-by-week strength block from a working load, reps, deload timing, and plate rounding with rule checks and a load curve.

Compare squat, bench, deadlift, or overhead press 1RM against bodyweight standards with recent-set estimates and source-reviewed targets.

Calculate waist-to-height ratio from mixed units, compare NICE and legacy bands, and translate half-height cutoffs into waist targets.

Calculate waist-to-hip ratio from waist and hip measurements, compare sex-specific bands, and test whether tape uncertainty could change the screen.

Plan a daily drink target from total-water references, food-water share, exercise sweat, serving size, caffeine, and safety flags.

Plan a weight-change target from body stats, activity, and goal timing, with calorie floors, BMI context, pace warnings, and runway charts.

Calculate a child's weight-for-age percentile from age, sex, and weight, with WHO/CDC chart context, corrected-age support, and follow-up cues.
