Muaj ntau txoj hauv kev uas tuaj yeem siv los hloov cov meters mus rau taw hauv lub network, tab sis yog tias qhov no yog tus kws qhia ntawv txoj haujlwm, feem ntau tus kws qhia ntawv yuav thov kom pom cov txheej txheem. Kawm txoj hauv kev yog qhov zoo thiab muaj txiaj ntsig, yog li koj tsis txhob ua yuam kev koj tus kheej. Yog tias koj xav hloov pauv square metres (m2) lossis cubic meters (m3), koj kuj yuav tsum hloov pauv mus rau square feet lossis cubic feet. Luckily, nws tsis nyuaj rau hloov nws yog tias koj nkag siab li cas.

Txoj Kev 1 ntawm 3: Hloov Cov Meters rau Taw
Kauj Ruam 1. Nkag siab tias ib lub 'meter' yog 3.28 ko taw
Ib lub 'meter' yog chav tsev ntev sib npaug li 3.28 ko taw. Koj tuaj yeem ntsuas qhov no siv ib tus ntsuas ntsuas ib meter thiab ib txhais taw (12 nti) tus kav. Muab tus ntsuas ib 'meter' rau hauv pem teb, thiab kab nws nrog tus kav ib txhais taw ntawm tib qhov kawg. Peb tus pas ntsuas (peb ko taw) yuav kwv yees ntev npaum li ib tus kav ib meter. Yog tias koj ntxiv tus kav ib-ko taw, koj tuaj yeem ntsuas qhov siab tshaj ntawm 0.28 ko taw, "me ntsis" ntev dua peb ntiv tes.
Yog tias koj xav tau kev ntsuas raug, koj tuaj yeem siv qhov hloov pauv ib 'meter' = 3.28024 ko taw. Txij li tus lej no txawv "me ntsis" los ntawm 3.28, nws yooj yim dua siv 3.28 hauv kev suav ua lej yooj yim
Kauj Ruam 2. Muab txhua qhov kev ntsuas hauv meters los ntawm 3.28 txhawm rau hloov lawv mus rau taw
Txij li ib lub meter = 3.28 ko taw, koj tuaj yeem hloov pauv txhua qhov kev ntsuas hauv meters mus rau ob txhais taw los ntawm kev sib tw los ntawm 3.28. Yog tias koj tsis paub meej yuav ua li cas, nyeem cov lej sib npaug. Muaj ntau qhov piv txwv ntawm no. Yog tias koj xav tau, koj tuaj yeem sim ua qhov kev suav koj tus kheej thiab pom tias koj tau txais cov lus teb raug:
- 1 m x 3, 28 = np 3.28ft ua
- Luas 5 m x 3,28 = 16, 4ft
- 2,7 m x 3, 28 = np 8,856m ua
Kauj Ruam 3. Hloov koj qhov kev ntsuas mus rau ntiv tes (xaiv tau)
Rau kev suav ua lej feem ntau, txhua yam koj xav tau yog lo lus kawg rau koj qhov kev suav. Tab sis yog tias koj xav paub txog kev ntsuas tiag, cov lus teb zoo li "8,856 ko taw" yuav tsis txaus siab rau koj. Sim ua kom tag nrho cov lej zauv uas koj tau txais, tom qab ntawd suav nrog 12 los hloov lawv mus rau ntiv tes. Qhov kev suav no raug vim tias ib txhais taw = 12 ntiv tes. Cov txheej txheem hloov dua siab tshiab yog tib yam li thaum hloov cov meters mus rau taw. Nov yog qee qhov piv txwv:
- 3.28 ko taw = 3 ko taw + 0.28 ko taw. Txij li 0.28 ko taw x 12 = 3.36, qhov no txhais tau tias 3.28 ko taw = 3 ko taw thiab 3.36 nti
- 16.4 ko taw = 16 ko taw + 0.4 ko taw. Txij li 0.4 ko taw x 12 = 4.8, qhov no txhais tau tias 16.4 ko taw = 16 ko taw thiab 4.8 nti
- 8.856 ko taw = 8 ko taw + 0.856 ko taw. Vim tias 0.856 ko taw x 12 = 10, 272, yog li 8, 856 ko taw = 10 ko taw thiab 10.272 nti
Txoj Kev 2 ntawm 3: Hloov Square Meters rau Square Taw
Kauj Ruam 1. Nkag siab txog square metres
Square meter, lossis feem ntau tseem sau m2 yog kev ntsuas thaj tsam. Thaj chaw tau siv los ntsuas ob-seem ntawm qhov chaw, xws li hauv pem teb ntawm chav, lossis chaw ncaws pob. Ib lub xwmfab yog ib lub xwmfab uas zoo ib yam li thaj tsam uas yog ib lub meter ntev thiab ib lub dav dav. Koj tuaj yeem hloov qhov ntsuas thaj tsam ntawm thaj chaw mus rau chav tsev ib yam nkaus, tsis txhob hloov nws mus rau chav ntev. Hauv qhov kev xam no, peb yuav hloov los ntawm cov square metres (m2) rau square feet.
Ib lub xwmfab yog ib lub xwmfab zoo ib yam ntawm thaj tsam uas yog ib txhais taw ntev thiab ib txhais taw dav
Kauj Ruam 2. Nkag siab tias vim li cas koj thiaj yuav tsum siv cov square feet
Hloov pauv cov square metres mus rau square feet tsis nyuaj. Zoo li hais tias "Kuv paub tias plaub lub xwmfab no txaus los npog hauv pem teb no. Tab sis yog tias lub xwmfab siv me dua, xav tau ntau npaum li cas? " Koj tsis tuaj yeem hloov thaj tsam mus rau qhov ntev (zoo li hauv metres mus rau ko taw), zoo li qhov no yuav zoo li nug "Ntev npaum li cas tus kav yuav siv los npog hauv pem teb no?" Txawm hais tias koj siv tus kav ntev npaum cas, nws tseem tsis tuaj yeem npog hauv av.
Kauj Ruam 3. Sib npaug cov square metres los ntawm 10, 8 kom hloov lawv mus rau square feet
Ib square meter tuaj yeem npog nrog 10.8 square feet. Qhov no txhais tau tias koj tuaj yeem muab txhua qhov ntsuas ntawm m2 nrog 10.8 kom tau txais kev ntsuas hauv ft2 (square xwmfab).
Yog tias koj xav kom koj qhov kev suav kom raug, muab nws suav nrog 10, 764
Txoj Kev 3 ntawm 3: Hloov Cov Cubic Meters rau Cubic Taw
Kauj Ruam 1. Nkag siab txog lub cubic meter
Cubic meters tau sau ua m3. Nws yog chav tsev ntim, uas ntsuas chav nyob hauv peb qhov ntev. Koj tuaj yeem siv cov ntsuas ntsuas ntsuas cua hauv chav, lossis dej hauv chav dej. Ib cubic meter yog qhov sib npaug ntawm lub voos xwmfab ib meter ntev, ib meter dav thiab ib meter siab.
Ib yam li ntawd, ib txhais taw ko taw yog sib npaug ntawm lub voos xwmfab nrog ntev ntawm ib txhais taw, dav ntawm ib txhais taw thiab qhov siab ntawm ib txhais taw
Kauj Ruam 2. Muab cov cubic cubic los sib npaug 35, 3 kom tau cov cubic feet
Ib lub cubic meter tuaj yeem haum 35.3 cubic feet hauv nws. Daim ntawv ceeb toom yog vim li cas tus lej no loj dua qhov hloov pauv uas koj tau siv ua ntej, nws yog square metres lossis ntsuas ib txwm. Vim tias koj muab tus lej hloov pauv "peb" lub sijhawm thaum koj tab tom suav hauv peb qhov ntev. Lub cubic meter yog 3.28 npaug ntev tshaj li ib lub cubic foot, tab sis kuj yog 3.28 npaug dav thiab 3.28 npaug siab dua. 3.28 x 3.28 x 3.28 = 35.3, yog li, ib lub cubic meter yog 35.3 npaug loj dua ntim ib cubic feet.
Rau kev suav kom raug dua, sib npaug los ntawm 35, 315
Lub tswv yim
- Yog tias koj xav hloov pauv los ntawm square feet mus rau square inches, muab sib npaug los ntawm 144. Ib square feet yog "12" lub sij hawm ntev dua thiab "12" lub sij hawm dav dua li cov square inches, yog li tag nrho yog 12 x 12 = 144 npaug loj dua.
- Yog tias koj xav hloov los ntawm cubic feet mus rau cubic inches, sib npaug los ntawm 1728 (12 x 12 x 12).
