Ib lub millimeter yog ib chav ntev uas yog ib feem ntawm cov qauv ntsuas hauv cov txheej txheem ntsuas. Ib lub millimeter sib npaug rau 1/1,000 ntawm ib lub 'meter'. Muaj ntau txoj hauv kev los xam cov millimeters. Txoj hauv kev yooj yim tshaj plaws thiab yooj yim tshaj plaws yog siv tus ntsuas ntsuas, uas twb tau sau npe nrog cov cim cim cim. Txoj hauv kev thib ob yog siv cov lej yooj yim los hloov nws los ntawm lwm qhov ntsuas, xws li centimeters, kilometers, inches, lossis yards.
Kauj ruam
Txoj Kev 1 ntawm 3: Siv Tus Thawj Coj Tus Thawj Coj
Kauj Ruam 1. Saib kab ntawv tsis cim rau ntawm tus ntsuas ntsuas
Muaj ob chav sib cais hauv tus qauv ntsuas ntsuas: centimeters thiab millimeters. Cov kab zauv cim qhia txog centimeters, thaum cov kab cim tsis yog sawv cev rau millimeters. Yog tias koj ua tib zoo saib, koj yuav pom tias 10 millimeters sib npaug rau 1 centimeter.
- Kab kab nruab nrab ntawm qhov nruab nrab nruab nrab ntawm txhua tus lej suav nruab nrab ib nrab ntawm ib centimeter, aka 5 millimeters.
- Cov ntawv cim npe no tseem siv rau lwm qhov ntsuas ntsuas ntev dua, xws li cov pas ntsuas thiab ntsuas kab xev.
Kauj Ruam 2. Teem qhov taub ntawm tus pas ntsuas nrog cov khoom koj xav ntsuas
Tshwj xeeb tshaj yog, tso kab ib cim "0" nrog rau ntug ntawm qhov khoom kawg. Xyuas kom tus pas ntsuas ncaj ncaj thiab haum rau qhov pib ntawm koj qhov kev ntsuas.
- Yog tias koj xav pom qhov ntev ntawm koj lub xov tooj nyob rau hauv millimeters, kho tus pas ntsuas kom kab "0" txuas mus rau kab rov tav kawg ntawm lub cuab yeej.
- Tsis yog txhua tus thawj coj muaj kab lej "0". Yog tias koj tus neeg saib xyuas zoo li qhov no, xav tias qhov kawg ntawm tus pas ntsuas mus rau sab laug ntawm kab ntawv suav "1" yog lub ntsiab lus "0 mm".
Kauj Ruam 3. Muab tus lej sib nrug ua ntej qhov kawg ntawm qhov khoom raug ntsuas los ntawm 10
Sau tus lej sib npaug centimeter kawg ntawm tus pas ntsuas. Muab tus lej no los sib npaug 10 los hloov nws mus rau millimeters thiab qhia qhov ntev ntawm qhov khoom hauv millimeters mus txog qhov ntawd.
Yog tias lub centimeter kawg yog 1, sib npaug 10 kom tau 10 vim tias 1 cm = 10 hli
Tswv yim:
Ib txoj hauv kev nrawm thiab yooj yim kom muab tus lej sib npaug los ntawm 10 yog tso "0" tom qab nws.
Kauj Ruam 4. Ntxiv cov naj npawb kab tom qab tus lej centimeter kawg
Tam sim no, suav tus naj npawb ntawm kab millimeter kawg uas nce mus txog qhov kawg ntawm qhov khoom. Cov kauj ruam no yog qhov tsim nyog vim tias cov kab ntawm kab uas nyob ib sab tsis txaus los ua kom puv 1 centimeter. Tsuas yog siv lub ntsuas ntsuas centimeter los xam qhov ntev ntawm cov khoom hauv millimeters kom txuag sijhawm.
- Yog tias qhov ntsuas tau ntsuas yog 1.5 cm ntev, sib npaug 1 txog 10 kom tau 10, thiab ntxiv 5 kom tag nrho qhov ntev yog 15 hli.
- Yog tias nws yooj yim dua, koj kuj tseem tuaj yeem ntsuas ib centimeter dhau los ntawm qhov kawg ntawm qhov khoom thiab rho tawm tus lej millimeters nyob nruab nrab. 2 centimeters (20 mm) rho tawm 5 millimeters yog 15 mm.
Txoj Kev 2 ntawm 3: Hloov Mus Rau Lwm Qhov Loj
Kauj Ruam 1. Kawm paub ntsuas cov ntsuas ntsuas ua haujlwm li cas thiaj tuaj yeem suav cov millimeters yooj yim
Raws li koj tuaj yeem pom, muaj 10 millimeters hauv ib centimeter. Ib yam li ntawd, muaj 1,000 millimeters hauv 1 meter thiab 1,000,000 millimeters hauv 1 kilometer, uas tseem sib npaug li 1,000 meters. Thaum koj nkag siab cov lej, hloov mus rau lwm qhov ntsuas ntsuas tau yooj yim.
Cov ntawv ua ntej “centi” txhais tau tias “ib puas,” uas txhais tau tias 1 centimeter yog 1/100 ntawm ib lub 'meter'. Zoo sib xws, "milli" txhais tau tias "txhiab", yog li 1 millimeter yog 1/1,000 ntawm ib lub 'meter'
Kauj Ruam 2. Muab ntiv tes xoo 25.4 los nrhiav qhov ntev hauv millimeters
Koj yuav xav tau lub laij lej rau qhov no. Pib los ntawm kev nkag ntiv tes mus rau ob tus lej tom qab ntawm zauv (piv txwv, 6, 25). Tom qab ntawd, nyem "x" tus lej thiab nkag tus lej "25.4" vim tias 1 ntiv tes sib npaug 25.4 millimeters. Nias tus "=" tus yuam sij, thiab koj yuav tau txais cov ntsuas sib xws, tab sis hauv millimeters.
- Siv cov piv txwv tham saum toj no, 6.25 ntiv tes sib npaug 158.75 mm.
- Hloov cov ntiv tes mus rau millimeters yog qhov nyuaj me ntsis ntau dua li lwm qhov kev hloov pauv vim tias cov ntiv tes yog cov chav tsis muaj vaj huam sib luag thiab millimeters yog cov chav ntsuas.
Tswv yim:
Hloov cov lej lej mus rau tus lej yuav tsum txaus. Yog tias koj xav tau qhov tseeb ntxiv, hloov mus txog ob tus lej tom qab tus lej
Kauj Ruam 3. Muab qhov ntsuas hauv ko taw los ntawm 304, 8
Lub tswv yim yooj yim yog tib yam li hloov cov ntiv tes rau millimeters. Muaj kwv yees li 304.8 millimetres hauv ko taw yog li muab kev ntsuas hauv ko taw los ntawm 304.8 txhawm rau nrhiav qhov loj ntawm kev ntsuas hauv qhov ntsuas me me tshaj plaws rau qhov ntev, uas yog millimeters.
Yog tias koj muaj 5 taw siab, koj qhov siab hauv millimeters yog 1,524 millimeters. Koj qhov siab yuav tshwm loj dua
Kauj Ruam 4. Siv qhov kev hloov pauv ntawm 914, 4 los hloov lub yards mus rau millimeters
Tsis muaj dab tsi txawv ntawm no. 1 yard yog sib npaug rau 914.4 millimeters. Raws li qhov tshwm sim, sib npaug 1 vaj los ntawm 914.4 kom hloov nws mus rau millimeters.
- Tib txoj hauv kev yooj yim rau kev hloov cov ntiv tes thiab taw mus rau millimeters siv ntawm no ib yam. Ib txhais taw sib npaug 12 ntiv tes yog li 12 x 25, 4 = 304, 8; 1 yard sib npaug 3 feet li 304, 8 x 3 = 914, 4, thiab ntxiv rau.
- Piv txwv li, kev ncaws pob ntawm American Football yog 100 yards. Yog hloov dua siab tshiab, qhov loj me no yog sib npaug rau 91,440 mm. Xav txog yog tias koj ntsuas nws siv tus pas ntsuas!
Txoj Kev 3 ntawm 3: Ntsuas Qhov Ntsuas Nrog Daim Npav Credit
Kauj Ruam 1. Siv daim npav rho nyiaj tsis tu ncua
Feem ntau daim npav rho nyiaj (thiab lwm yam ntawm daim npav yas) yog 30 lab tuab, uas yog li 0.76 hli (lossis 0.762 hli kom raug). Nws tsis yog qhov ntsuas qhov tseeb tshaj plaws, tab sis nws txaus yog tias koj tsuas xav tau kwv yees kwv yees qhov ntev ntawm qee yam hauv millimeters
- Yog tias koj tsis muaj daim npav rho nyiaj, sau 10 nplooj ntawv ntawm 22 cm x 28 cm ntawv luam ntawv kom tau 1 mm tuab. Txawm li cas los xij, txoj hauv kev no tuaj yeem nyuaj dua li daim npav yas.
- "Mais" yog chav tsev tsis muaj vaj huam sib luag uas yog 1/1,000 ntawm ib nti, thiab yuav tsum tsis txhob meej pem nrog ib lub hli.
Ceeb toom:
Txij li cov txheej txheem no tsuas yog tsim qhov kwv yees ntxhib, tsis txhob siv nws yog tias koj xav tau kev ntsuas raug.
Kauj Ruam 2. Sawv ntsug daim npav ntawm ib daim ntawv uas nyob ib sab ntawm qhov khoom ntsuas
Txhim kho sab nrauv ntawm daim npav nrog qhov pib xaiv ntawm lub hom phiaj. Xav txog daim npav no ua tus kav, thiab cov npoo yog 0 hli kab.
Txog txoj hauv kev no, koj yeej tseem ntxiv 1 mm txhua lub sijhawm los nrhiav qhov loj ntawm cov khoom sib xws
Kauj Ruam 3. Siv tus cwj mem los xaum los kos kab nyias rau ntawm daim npav sab hauv
Rub lub taub hau ntawm koj cov tais diav ntim rau ntawm ntug daim npav kom tsim kab ncaj uas ntev txaus kom pom tau meej. Kab no sawv cev rau qhov nrug deb ntawm 0.762 millimeters ntawm qhov kawg ntawm qhov khoom thiab thawj kab.
Koj yuav tau kos tus lej ntawm kab uas nyob ze ua ke yog li nias maj mam thiab ua kab kom nyias li sai tau. Hnov tus cwj mem los yog siv tus cwj mem taw qhia kom ua txoj haujlwm yooj yim dua
Kauj Ruam 4. Tsiv daim npav tom ntej ntawm kab kab ntawv thiab rov ua cov txheej txheem
Kab ntawv no yuav cim lub ntsiab lus 1.52 hli los ntawm qhov pib ntawm qhov ntsuas. Tsiv daim npav mus rau lwm sab ntawm kab kawg, thiab kos lwm kab. Txuas ntxiv ntsuas thiab kos cim me ntsis kom txog thaum koj mus txog qhov kawg ntawm qhov khoom, tom qab suav tus lej ntawm txhua qhov sib txawv ntawm txhua kab.
- Nco ntsoov koj suav qhov chaw nruab nrab ntawm kab thiab tsis yog kab lawv tus kheej vim tias cov kab yuav ntau dua 1.
- Txhawm rau ntxiv qhov tseeb, suav txhua 4 kab ua 3 mm. Qhov ua kom yuam kev no yuav pab nrog koj ntsuas vim tias daim npav rho nyiaj tsis tuab 1 hli tuab.
Lub tswv yim
- Paub paub ntsuas li cas hauv millimeters yog qhov txuj ci muaj txiaj ntsig. Qhov ntau ntawm cov khoom lag luam thiab cov khoom tshwj xeeb, feem ntau hais tawm hauv millimeters, suav nrog cov cuab yeej thiab cov khoom siv hauv tsev, cov khoom siv hluav taws xob, tsom iav qhov muag, thiab cov hniav nyiaj hniav kub.
- Tam sim no lub ntsuas ntsuas tau paub los ntawm lwm lub npe: International System of Units (luv rau SI). Txawm li cas los xij, ob lub npe no hais txog tib chav ntsuas.
