Estimate body-fat percentage from tape measurements, compare Navy, RFM, and BMI-age methods, and plan lean-mass, waist, and target-weight checks.

Calculate adult BMI from height and weight, compare WHO, Asia-Pacific, and NIH/CDC bands, and add waist and target-weight context.

Compare BMI, waist ratios, body-fat estimates, lean and fat mass, BSA, and reference weights with risk bands and spread warnings.

Plan a body recomposition target from weight, body-fat change, lean-mass assumptions, runway, calories, protein, and uncertainty flags.

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.

Build a pediatric growth report from visit rows with percentiles, BMI, height velocity, screening flags, charts, and follow-up guidance.

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

Check child growth visits for percentile drift, corrected age, height velocity, adiposity, and family-height flags with triage guidance.

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 intermittent fasting windows from a first meal time, with safety ceilings, weekend shifts, hydration reminders, and downloadable schedules.

Estimate lean body mass from height, weight, sex, and body-fat checks, then compare formula spread, FFMI, warnings, and charts.

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.

Calculate pregnancy weight gain from pre-pregnancy BMI, gestational age, singleton or twin pregnancy, and current gain with week-to-date guidance.

Estimate a child's projected adult height from standing height, age, sex, and parent heights, with scenario ranges and family-band checks.

Calculate a daily protein target from body weight, goal, training load, diet pattern, meals, and health context, with gap and calorie-share checks.

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

Estimate active calories from steps with weight, step length, pace, terrain, target steps, and uncertainty ranges for walks or runs.

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

Compare your squat, bench, deadlift, or press 1RM against bodyweight standards with recent-set estimates, target deltas, and source notes.

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

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

Plan a daily drink target from total-water references, body weight, climate, exercise, sweat data, serving counts, and safety flags.

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

Calculate a child's weight-for-age percentile with WHO/CDC references, corrected-age handling, z-score context, alert lanes, and follow-up cues.

Calculate weight-for-length percentile from infant weight and length, compare WHO/CDC references, and review z-scores, source fit, and target weights.

Calculate workout volume from training rows, compare tonnage with hard-set targets, and account for external and bodyweight-equivalent load.
