How Much Weight Should a Baby Gain? WHO Monthly Guide
Baby weight gain is fastest in the first two months: a healthy baby gains about 1 kg a month, then a little less each month after that. The WHO child growth standards put the median gain for boys at 1,023 g in the first 4 weeks and 239 g between 11 and 12 months; for girls the figures are 879 g and 232 g. A doctor judges a baby's growth from the trend over several visits, not from one month's number.

Boys Growth Chart: WHO Height and Weight, Birth to 5 Years
A growth chart for boys compares a boy's weight and height with healthy boys of the same age on the WHO child growth standards. On those standards, the median boy weighs 3.3 kg at birth, 12.2 kg at 2 years and 18.3 kg at 5 years, and his height rises from 49.9 cm to 110.0 cm. The Indian Academy of Pediatrics recommends the WHO charts for children under 5, and a doctor reads the trend across visits.

Head Circumference Chart: WHO Normal Range by Age
A baby's head circumference is normal when it sits within the range for the baby's age and sex on the WHO child growth standards. At birth the WHO median is 34.5 cm for boys and 33.9 cm for girls, with a 3rd to 97th percentile range of 32.1–36.9 cm for boys and 31.7–36.1 cm for girls. The head grows 11–12 cm in the first year and only about 2 cm in the second.

Weighing Scale vs Balance: Which Is Better for You?
A weighing scale measures the pull of gravity on a load and shows it as mass, while a balance compares the load with a known mass. A scale suits everyday loads from grams to tonnes, and a balance suits milligram work: Omace's Ace balances read in 1 mg steps up to 200–500 g, while its shop scales weigh 10–30 kg in 1–5 g steps.

How to Use an Infantometer: Steps, Age Range and Accuracy
An infantometer measures a baby's length lying down, and it is used from birth until about 2 years of age. The WHO growth-assessment course measures every child under 2 this way, with two people: one holds the head against the fixed headboard, and the other straightens the legs and slides the footboard against the feet. The length is read to the last completed 0.1 cm.

How Does a Bathroom Scale Work? Meaning and Accuracy
A bathroom scale is a floor scale for checking your body weight at home, and it works by measuring the force your body presses onto its platform. A digital bathroom scale senses that force with strain gauge sensors and shows it in 100 g steps up to 180 kg; an analog one moves a needle with a spring, on a dial marked every 500 g.

How to Measure Height Accurately: Tools and Steps
To measure height accurately, stand barefoot against a stadiometer or a flat wall and lower a flat headpiece onto the top of your head. Your heels, buttocks, shoulder blades and the back of your head touch the board, and your eyes look straight ahead. The WHO growth assessment course records height to the last completed 0.1 cm, which is 1 mm. Measure at the same time of day each time, because height drops slightly in the hours after you get up.

What Is a Stadiometer? Uses, Types and How to Use One
A stadiometer is an instrument that measures a person's standing height. It has a vertical measuring scale, a flat headpiece that slides down onto the top of the head, and a base or wall fitting that keeps the scale upright. The WHO growth assessment course calls it a height board and records the reading to the last completed 0.1 cm, which is 1 mm. It is used for anyone who can stand, usually from age 2; babies are measured lying down on an infantometer.

How to Calibrate a Digital Weighing Scale at Home
To calibrate a digital weighing scale, zero it on a firm, level surface, enter its calibration mode and place the exact test weight the display asks for. The scale stores that weight as its new reference and confirms with PASS, CAL or the weight value. OIML R 76, the international recommendation for non-automatic scales, says a test weight's error must be no more than one third of the scale's permitted error. Scales used for trade in India must also be verified and stamped by the Legal Metrology department, which home calibration does not replace.

How Does a Smart Scale Measure Body Fat? BIA Explained
A smart scale measures body fat with bioelectrical impedance analysis (BIA): it sends a tiny electrical current through your body and measures how strongly the tissue resists it. A review in Nutrition Journal puts the usual signal at about 800 microamps and 50 kHz. Water-rich lean tissue conducts that current easily, while fat resists it. The scale turns the resistance, plus your height, age and sex, into an estimated body fat percentage.

OIML R 76 sets the minimum load of a class III scale at 20 steps, so a scale that reads in 100 g steps should not be used below 2 kg.

Under OIML R 76, the price to pay must equal the displayed weight times the unit price per kg or per 100 g, rounded to the nearest price step. Test the weight first, because a weighing error flows into every bill.

A hospital or clinic scale is calibrated by weighing certified test weights at several loads, checking the corners and repeat readings, and correcting any error.

Staff should also check zero before every patient.

To calibrate a pocket scale, set it on a firm, still surface, let it settle at 0.00, enter calibration mode and place the exact weight the display asks for.
