Malunga nale Calculator
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 ebuza rhoqo
Ichanekile njani indlela yoMkhosi wamanzi?
Ihlala imalunga ne-3-4% ye-DEXA scan kuninzi lwabantu. Umgangatho uxhomekeke ekubeni uvavanyo luqhutywe kwiindawo ezifanelekileyo ngetephu eqinileyo kodwa ngaphandle kokucinezela isikhumba.
Yintoni iphesenti yobude benyama ekhuselekileyo?
Iindawo eziqhelekileyo zokuzivocavoca zimalunga ne-14-24% zamadoda ne-21-31% zamadoda kodwa iindawo ezifanelekileyo zokuzivocavoca zitshintsha ngokweminyaka kunye nenjongo yokudlala imidlalo.
Ndiyilinganise phi ngokucacileyo?
Uvavanyo lwe-teip luya kuvavanywa kwingcambu engaphantsi kwe-larynx, kwi-waistline ethe tyaba kwi-navel (kwindawo encinci kakhulu yabasetyhini), kwaye kwi-hips yabasetyhini kwindawo ebanzi kakhulu. Gcina i-teip iphakame kwaye ihlale ikhululekile ngaphandle kokucinezela isikhumba ukuze ufumane isiphumo esithembekileyo.
Kutheni amadoda afuna ukulinganisa ithambo lengalo?
Ifomula yoMkhosi wamanzi yabasetyhini isebenzisa umva, intamo, imilenze kunye nobude, ngenxa yokuba unikezelo lobunzima bomzimba bamabhinqa buhlukile kumadoda. Ifomula yabasetyhini isebenzisa kuphela umva, intamo kunye nobude, ngoko ke i-hip field ifuneka kumabhinqa kwaye ayihoywa kumabhinqa.
Uphi na utshintsho olukhoyo phakathi kophesenti lobunzima bomzimba kunye ne-BMI?
I-BMI imele kuphela ubunzima obuhambelana nobude kwaye ayikwazi ukuchaza ubunzima bomzimba kunye ne-muscle, ngelixa indlela yoMkhosi wamanzi iqikelela ubungakanani besisindo somzimba ngokusebenzisa ubungakanani besikhumba. Abantu ababini abane-BMI efanayo banokuba neepesenti zesisindo somzimba ezihlukileyo kakhulu.
Yintoni ubunzima bomzimba obunobunzima obuninzi kunye nobunzima bomzimba obuncinci?
I-fat mass yipesenti yobunzima bomzimba obunzima benyama yakho esetyenziswe kubunzima bakho; i-lean body mass yiyo yonke into—i-muscle, i-bone, i-organs kunye namanzi. Faka ubunzima bakho phantsi kwezinto ezikhethwayo eziphambili kwaye i-calculator iya kuxela zombini.
