Hundredweight - yog ntau npaum li cas?

Nyob rau hauv lub neej txhua hnub yog tsis yog ua hauj lwm nrog cov lus "quintal", "his", "phaus". Tab sis tej zaum koj yuav tau hloov lub luj mus rau lwm yam units ntawm kev ntsuas los yog xam nws nyob rau hauv lawv. Tej yam yooj yim cov kev ua yuav pab tau tswvyim.

Yuav ua li cas yog hundredweight

Lo lus los ntawm German thiab lus txhais tau tias "puas kauj ruam". Nws tshwm sim los ntawm Latin centum - ib tug puas. Standard qho qos hnab, uas nyhav ib quintal. Tab sis nws yog txawv nyob rau hauv txawv xeev ntawm lub teb chaws Yelemees:

• Nyob rau hauv Bavaria - 56 kilograms.
• Nyob rau hauv Saxony - 51,4 kg.
• Nyob rau hauv Braunschweig - 46,77 kg.

Tom qab ntawd nyob rau hauv lub teb chaws no peb coj lub nruab nrab tus nqi quintal 50 kg.

Thaum cov lag luam tawm pib los tsim, tshwj xeeb tshaj yog nyob rau hauv lub hiav txwv kev, nws tau los ua tsim nyog los coj tag nrho cov kev ntsuas ntawm qhov ceeb thawj nyob rau hauv ntau lub teb chaws mus rau tib system. Ua li no, muaj cov conversion ntxhuav los ntawm ib tug dimension mus rau lwm lub.

• Metric, los yog ob hundredweight - yog 100 phaus, raws li nyob rau hauv Austria, Spain, Fabkis thiab Portugal. Nws yog sib npaug zos rau 100 kilograms.
• Nyob rau hauv Russia quintal yog 100 kilograms. Uas yog ib feem kaum ntawm ib tug ton.
• Hundredweight nyob rau hauv ces, lub teb chaws Yelemees, Switzerland, Hungary thiab Denmark yog 50 kilograms. Qhov no yog ib qho quintal.

Nyob rau hauv lub metric system, uas ua hauj lwm pab raws li tus txheej txheem ntev ntsuas 'meter', tus luj ntawm ib lab cubic meters ntawm cov dej (gram) saws raws li tus txheej txheem ntawm kev ntsuas ntawm qhov ceeb thawj. Ib tug qauv ntawm 1000 grams yog hu ua ib tug kilogram, qhia tshwj xeeb uas ntiab tawm ntawm platinum thiab iridium thiab yog khaws cia nyob rau hauv Paris. Thiab nyob rau hauv 1885, kaum xya lub teb chaws nrhiav tau lub International Bureau of tes taw hnyav li thiab ntsuas.

Cov nram qab no tau raug muab tshem nyob rau hauv lub SI system:

• Hundredweight - ib puas kilograms.
• Kilogram - yog ib txhiab grams.
• Tuj - ib txhiab kilograms.

Yuav ua li cas hloov hnyav rau kilograms centners

Yuav kom muab tso centners nyob rau hauv kilograms, tus nqi yuav tsum tau ib yam dab tsi nyob rau hauv centners khoo los ntawm ib tug puas. Nws nkawd yooj yim, yog hais tias tus naj npawb ntawm cov quintals - integer. Thiab yog hais tias tsis?

piv txwv:

• 1 n = 1 x = 100 kg 100 kg.
• Q = 1.3 1.3 x 100 kg = 130 kg.
• 0.4 q = 0, x 4 = 100 kg 40 kg.

Rau simplicity, koj muaj peev xwm xaiv nyias quintal, thaum tus neeg txhais lus ntawm quintal mis nyob rau hauv kilograms yuav tsum:

• A p = ib tug x 1 A x y = 100 kg

Qhov twg A - xov tooj (integer los yog fractional, decimal los yog tsis).

Yuav ua li cas mus rau 1 ton

• Quintals - 10.
• Kg - 1000.
• Grams - 1000000.

Lo lus "tuj" nyob rau hauv Latin, twb xaiv ib chim. Ib yam li nrog quintals, tons twb sib txawv. Tab sis nyob rau hauv lub SI system nws yog lam xav tias nyob rau hauv ib tug ton ntawm 10 quintals.

Yuav kom muab tso centners nyob rau hauv tonnes, tus nqi yuav tsum tau ib yam dab tsi nyob rau hauv centners muab faib los ntawm kaum.

piv txwv:

• 1 n = 1/10 = 0.1 m.
• 1.3 q = 1,3 / 10 = 0,13 m.
• 0.4 q = 0, 4/10 = 0.04 m.

translation ntawm mis quintal nyob rau hauv tons:

• A p = ib tug x 0, t 1 = A / 10 m

Qhov twg A - xov tooj.

Yuav ua li cas mus txhais ua centners

Nyob rau hauv centners txhais kilograms, grams thiab tons.

1. kilograms: Kom hloov kilograms rau quintals tooj yuav tsum dab tsi nyob rau hauv kilograms muab faib los ntawm ib tug puas.

piv txwv:

• 10 kg = 10/100 = 0.1 n c.
• 100 kg = 100/100 = 1 n q.
• 653 kg = 653/100 = 6.53 n n.
• 1 kg = 1/100 c = 0.01 q.
• 1.3 = 1.3 kg / 100 p = 0,013 p.
• 0.4 = 0.4 kg / 100 p = 0,004 p.

translation mis ntawm kilograms centners:

A = kg ntawm A / 0.01 q = A / 100 q.

2. Grams: Kom hloov grams ib hundredweight, tus nqi yuav tsum tau ib yam dab tsi nyob rau hauv grams muab faib los ntawm ib puas txhiab.

piv txwv:

• 10 gram = 10/100 000 p = 0,00001 c.
• 100 g = 100/100 000 p = 0,0001 p.
• 653 grams = 653/100 000 p = 0,000653 u.
• 1 gram = 1/100 000 p = 0,000001 u.
• 1.3 g = 1.3 / 100 000 p = 0,0000013 y.
• = 0.4 gram ntawm 0.4 / 100 000 y y = 0,0000004.

Neeg txhais lus ntawm Formula grams centners:

Ib tug r = ib tug x 0, y = 00001 A / n 100000

3. Tons: Kom hloov tonnes ib hundredweight, tus nqi yuav tsum tau ib yam dab tsi nyob rau hauv tons khoo los ntawm kaum.

piv txwv:

• 10 m = 10 x 10 n = 100 n.
• 100 m = 100 n = 10 x 1000 p.
• 653 m x 10 = 653 n = 6530 n.
• 1 tuj = 1 x 10 n = 10 n.
• 1.3 m = 1.3 x 10 n = 130 n.
• 0.4 m = 0.4 x 10 n = 4 n.

translation ntawm mis tons centners:

Ib tug t = ib tug x 10 u.

Phau ntawv hloov lwm lub tsev ntawm qhov ceeb thawj kev ntsuas

Rau yooj yim ntawm kev xam hloov cov kev cai yuav tsum sau ua ke nyob rau hauv lub rooj.

Yuav ua li cas siv lub rooj:

Nyob rau hauv cov huab sab laug kem peb nrhiav ib qho kev ntsuas ntawm qhov ceeb thawj uas yuav tsum tau pauv mus rau lwm lub. Lub sab saum toj kab - kem npe. Qhov no hais txog, nyob rau hauv dab tsi ntsuas neeg txhais lus.

piv txwv:

1. Muab 15.6 quintal. Nws yog tsim nyog los txhais tus luj mus rau hauv kilograms.

• Tshuaj: Txiav txim seb lub leftmost kem "centners" nyob rau hauv lub saum toj kab tab tom nrhiav rau, dab tsi yuav tsum tau txhais - "rau kilograms," nyob rau hauv cov kev tshuam ntawm saib - yuav tsum tau khoo los ntawm ib tug puas. Yog li ntawd: 15.6 x 100 = 1560. Txij thaum lub siab los ntseeg kilograms, teem "kg".

2. Muab 450 grams. Peb yuav tsum txhais rau hauv tons.

• Tshuaj: Txiav txim seb tus luj ntawm lub predetermined twg - grams. Peb tab tom nrhiav rau sab saum toj kab ntawm lub ntsuas, uas yuav tsum tau txhais - "rau tons", ntawm cov kev tshuam ntawm pom: nws yog tsim nyog los faib ib tug lab. Yog li ntawd: 450/1 000 000 = 0,00045 m.

3. Muab 14,25 kilograms. Peb yuav tsum txhais rau hauv centners thiab tons.

Tshuaj: Nyob rau hauv rau sab laug kem tab tom nrhiav rau dab tsi yog muab - "kgs". Ces, nyob rau hauv lub saum toj kab yog "nyob rau hauv centners", ntawm cov kev tshuam peb pom tias yuav tsum tau muab faib mus rau hauv ib puas. Yog li ntawd: 14,25 / 100 = 0,1425 q. Nyob rau hauv tib txoj kev uas peb nrhiav tau lub "rau tons" - pom tau tias koj yuav tau faib los ntawm ib txhiab. Yog li ntawd: 14,25 / 1000 = 0,01425 m.

Nyob rau hauv thiaj li tsis mus yam txoj kab, piv txwv li, tsis txhob txhais mus rau hauv tons ntawm grams, yuav tsum pib nrog lub leftmost kem. Ces mloog mus rau lub sab saum toj kab. Nws yog tsis muaj kev huam yuaj yog tsim nyog lub preposition "nyob rau hauv". Qhov no yuav pab kom ib tug xaiv.

Txhais mus rau hauv ib tug ib qho kev ntsuas

Tej zaum nws yog tsim nyog los ntxiv, rho tawm, piv rau qhov tseem ceeb qhia los ntawm txawv ntsuas ntawm qhov ceeb thawj. Nyob rau hauv cov ntaub ntawv no lawv coj tuaj rau tus tib neeg.

piv txwv:

1. Muab: Piv quarter hundredweight thiab ib tug peb lub hlis twg ntawm ib tug ton.

Tshuaj: Ua ntej peb muab tag nrho rau tus tib neeg. Piv txwv li, nyob rau hauv kilograms. Peb yuav tsum txhais tau mus rau hauv ib tug peb lub hlis twg ton. Nyob rau hauv lub kab "tons" tab tom nrhiav rau cov kev tshuam ntawm ib kem "nyob rau hauv centners", peb pom hais tias nws yog tsim nyog los muab los ntawm kaum. T 1/4 x 10 = 27.5 y. Piv: 1/4 n rau 1/4 t = ¼ q thiab q = 27,5 thiab 27,5 q 0.25 q. Nws yog tseeb hais tias cov thib ob nqi yog ntau dua.

Nrog ib tug me ntsis kev xyaum, koj yuav kawm tau li cas kom sai txhais ib tug luj ntsuas mus rau lwm lub. Tab sis kawm kom paub yuav ua li cas muaj ntau yam grams, kilograms, tons ib tuj los tseem muaj. Thiab nco ntsoov hais tias ib tug hundredweight - ib puas kilograms.
