Iziphetho zivuselelwa uma ubhala.
Malunga nale khadi
This calculator estimates body fat percentage using the U.S. Navy circumference method, which needs only a tape measure. It feeds your height, neck and waist measurements — plus hip for women — into the Navy formula, which uses the ratio between these circumferences to estimate how much of your body is fat. Enter your weight too and it also splits that into fat mass and lean body mass.
For example, a man 175 cm tall with a 38 cm neck and an 85 cm waist comes out at roughly 17% body fat, which sits in the fitness range. Measuring accurately matters: keep the tape snug but not compressing the skin, take the waist at the navel and the neck just below the larynx.
Use it as a free, at-home alternative to calipers or a DEXA scan for tracking fat loss or muscle gain over weeks and months. It is an estimate, typically within a few percent of a lab measurement, so focus on the trend between measurements rather than any single reading.
Imibuzo ebuzwa kaningi
Ingabe indlela yeNavy ilungile?
Ivame ukuba phakathi kuka-3-4% we-DEXA scan kubantu abaningi. Ukunemba kuxhomekeka ekulinganiseni emaphethelweni afanele nge-tape eqinile kodwa hhayi ukucindezela isikhumba.
Yini iphesenti elifanele lokudla?
Izinga elijwayelekile lokuzivocavoca liyi-14-24% kubantu besifazane kanye ne-21-31% kubantu abadala, kodwa izinga elijwayelekile lihluka ngokuya ngobudala nobude benhloso yokudlala.
Ngawaphi amanani entengo?
Ukuhlolwa kwekhanda ngezansi kwe-laryng, i-waistline ngokuqondile e-navel (engxenyeni encane kakhulu yabesifazane), futhi kwabesifazane ama-hips engxenyeni ebanzi kakhulu. Gcina i-tape level futhi i-snug ngaphandle kokucindezela isikhumba ukuze uthole imiphumela ethembekile.
Kungani abesifazane bedinga ukulinganiselwa kwe-hip?
I-Navy formula for women uses waist, neck, hip and height together, because women’s fat distribution differs from men’s. The men’s formula uses only waist, neck and height, so the hip field is required for women and ignored for men.
Uyini umehluko phakathi kwe BMI nephesenti lesisindo somzimba?
BMI ilingana kuphela nesisindo-nobude bokubalingani futhi ayikwazi ukuchaza i-fat kusuka kuma-muscles, ngenkathi indlela yeNavy ilinganisela i-real proportion ye-fat usebenzisa ukulinganiselwa kwe-body. Abantu ababi abane-BMI efanayo bangaba ne-body fat percentages ezahlukene kakhulu.
Yini i-fat mass ne-lean body mass?
Isisindo se-fat siyingxenye yesisindo sakho esisetshenziswayo; isindo se-lean siyizinto zonke ezikhona — amathambo, amathambo, ama-organs nama-water. Faka isindo sakho ngaphansi kwezinketho ezithuthukisiwe futhi i-calculator ikhombisa izibalo zombili.
