Uma ucindezela umoya ongu-1 emoyeni, izinga lokushisa le-ice point le-thermometer ye-Celsius lingu-0^oC, kanti i-thermometer Isikali se-Fahrenheit singama-32^oF. Uma umoya ucindezelekile womoya ongu-1, izinga lokushisa lephuzu lomhwamuko le-thermometer ye-Celsius lingu-100^oC, kuyilapho i-thermometer yesikali se-Fahrenheit ingu-212^oF.
Ngakho-ke 0^oC=32^oF kanye ne-100^oC=212^oF.

^{Esikalini se-Celsius, kukhona ama-degree} ayi-100 phakathi kuka-0 ^° C no-100 ^° C. Esikalini se-Fahrenheit, kukhona ^{ama-degree ayi-180 phakathi kuka-32 °} F no-212 ^° F. Ukuze uthole izinga lokushisa le-Fahrenheit (T ^° F), qala ngokuphindaphinda izinga lokushisa le-Celsius (T ^° C) ngo-9/5 bese ufaka ^{ama-degree angu-32.}

T^oF = (180/100) T^oC + 32
T^oF = (9/5) T^oC + 32
T^oF = (9/5) 50 + 32
T^oF = (9) 10 + 32
T^oF = 90 + 32
T^oF=122

50 ^o C = 122 ^o F

2. 86^oF = ….. ^oC ?

Ukuthola izinga lokushisa ngesikali se-Celsius (T)^oC), nciphisa izinga lokushisa esikalini se-Fahrenheit ngo-32 (T^oF – 32) bese uphinda-phinda ngo-5/9.

T^oC = (100/180)(T^oF – 32)
T^oC = (5/9)(T^oF – 32)
T^oC = (5/9)(86 – 32)
T^oC = (5/9)(54)
T^oC = (5)(6)
T^oC=30

^{Ama-degrees Celsius angu} -86 Fahrenheit alingana nama -degrees Celsius ^{angu -30}

3. 50^oC = ….. K ?
Ingxoxo
T = T ^oC + 273
T = 50 + 273
T = 323

50 oC = 323 Kelvin

4. 212^oF = ….. K ?
Ingxoxo
Guqula izinga lokushisa esikalini se-Fahrenheit libe yi-Celsius, bese uguqula izinga lokushisa esikalini se-Celsius libe yi-Kelvin.
T^oC = (100/180)(T^oF – 32)
T^oC = (5/9)(T^oF – 32)
T^oC = (5/9)(212 – 32)
T^oC = (5/9)(180)
T^oC = (5)(20)
T^oC=100

^{Ama-degrees Celsius angu} -212 Fahrenheit alingana nama -degrees Celsius ^{angu -100}

T = 100 + 273
T = 373 Kelvin

Indlela 1: Ukusebenzisa Ifomula yokuguqulwa kwesikali se-Celsius kuya ku-Fahrenheit

Indlela 2: Ukusebenzisa ifomula yokuguqula isikali se-Fahrenheit kuya ku-Celsius

6. Umfundi ulinganisa izinga lokushisa lamanzi esebenzisa ama-thermometer amabili njengoba kuboniswe esithombeni. Uma izinga lokushisa lamanzi elilinganiswa ku-thermometer ye-Celsius linjengoba liboniswe esithombeni, izinga lokushisa ku-thermometer ye-Fahrenheit li….

A. 60^oF

B. 108 ^o F

C. 140 ^o F

D. 172 ^o F

Izinga lokushisa leqhwa le-thermometer ye-Celsius lingu-0 ^o C, kanti le-thermometer ye-Fahrenheit lingu-32 ^o F. Izinga lokushisa le-steam le-thermometer ye-Celsius lingu-100 ^o C, kanti le-thermometer ye-Fahrenheit lingu-212 ^o F.

Ngakho-ke u-0 ^o C = 32 ^o F kanye no-100 ^o C = 212 ^o F.

Esikalini se-Celsius, phakathi kuka-0^oC kuya ku-100^oI-C iqukethe i-100^o. Esikalini se-Fahrenheit, phakathi kuka-32^oF kuya ku-212^oI-F iqukethe u-180^o. Ukuze uthole izinga lokushisa esikalini se-Fahrenheit (T)^oF), qala ngokuphindaphinda izinga lokushisa esikalini se-Celsius (T)^oC) ngo-9/5 bese ufaka u-32^o

Kuya ^ku- F = (180/100) Kuya ^ku- C + 32

Kuya ^ku- F = (9/5) Kuya ^ku- C + 32

Kuya ^ku- F = (9/5) 60 + 32

Kuya ^ku- F = (9) 12 + 32

Kuze ^{kube ngu-} F = 108 + 32

Kuze ^{kube ngu-} F = 140

60 ^o C = 140 ^o F

Impendulo efanele ngu-C.
