Kauj Ruam 3. Muab cov txiaj ntsig los ntawm 5/9 kom tau txais qhov ntsuas kub hauv Kelvin

Nco ntsoov tias 5/9 tuaj yeem sau ua 0.55, nrog 5 yog rov ua zauv zauv. Cov lus teb rau qhov kev sib ntxiv no yog ntsuas kub hauv Kelvin.

  • Hauv 75 ° F piv txwv, cov lus teb rau theem ob yog 5/9 x 534.67 = 297.0388, nrog 8 yog tus lej zauv rov ua dua.
  • Cov lus teb rau kev suav (75 ° F + 459.67) x 5/9 yog 297.0388
  • Yog li, 75 ° F yog sib npaug rau 297.0388 K

Kauj Ruam 1. Kawm cov mis

Txoj hauv kev thib ob los hloov Fahrenheit rau Kelvin cuam tshuam thawj zaug hloov mus rau Celsius. Txoj hauv kev no ua rau koj yooj yim dua thaum koj yuav tsum sib piv qhov ntau thiab tsawg ntawm txhua chav nyob ntawm qhov ntsuas. Muaj ob tus qauv uas tuaj yeem siv los hloov Fahrenheit rau Celsius, tom qab ntawd mus rau Kelvin. Thawj mis (1) yog K = (qhov ntsuas kub ° F - 32) x 5/9 + 273, 15. Lub caij no, tus lej thib ob (2) yog K = (qhov ntsuas kub ° F - 32) 1, 8 + 273, 15. Ob tus qauv yuav muab cov txiaj ntsig zoo ib yam lossis lus teb.

  • Piv txwv li, yog tias koj xav hloov 90 ° F rau Kelvin siv tus lej 1, kev txhais lus yuav zoo ib yam li no: K = (90 ° F - 32) x 5/9 + 273, 15.
  • Rau cov mis 2, kev txhais lus yog ib yam zoo li no: K = (90 ° F - 32) 1, 8 + 273, 15.

Kauj Ruam 2. Txo qhov ntsuas kub thawj zaug los ntawm 32

Txawm hais tias siv cov mis twg, thawj kauj ruam los hloov Fahrenheit rau Celsius, tom qab ntawd rau Kelvin yog thawj zaug rho tawm 32 los ntawm thawj Fahrenheit.

Hauv qhov piv txwv piv txwv (90 ° F), cov lus teb rau thawj kauj ruam yog 90 ° F-32 = 58
