Satuan	Nilai	Definisi
kelvin (K)	310.15	Satuan dasar
derajat Celsius (°C)	37	K = °C + 273.15, tepat
derajat Fahrenheit (°F)	98.6	K = (°F + 459.67) × 5/9, tepat
degree Rankine (°R)	558.27	1 °R = 5/9 K, tepat
degree Réaumur (°Ré)	29.6	K = (°Ré + 218.52) × 5/4, tepat

Cara menghitung S

Konversi derajat Celsius ke kelvin
$37 + 273.15 = 310.15\ \text{K}$
K = °C + 273.15, tepat
Konversi kelvin ke derajat Fahrenheit
$310.15 \div \tfrac{5}{9} - 459.67 = 98.6\ \text{°F}$
K = (°F + 459.67) × 5/9, tepat
Pergeseran selain faktor skala
Skala suhu memiliki titik nol yang berbeda, sehingga konversi menambahkan selisih titik nol selain mengubah skala. Selisih suhu 1 °C sama dengan 1.8 °F.
Kedua satuan didefinisikan secara eksak dan nilai hasil konversi merupakan desimal berhingga, sehingga setiap digit yang ditampilkan bersifat eksak.

Tentang Konverter suhu

Temperature scales differ in the size of a degree and in where zero sits, so a conversion adds an offset as well as multiplying: °F = °C × 9/5 + 32, and K = °C + 273.15. The converter works through kelvin, whose zero is absolute zero, and rejects any value below it (−273.15 °C or −459.67 °F).

The default converts normal body temperature: 37 × 9/5 + 32 = 98.6 °F. Weather forecasts, oven settings and fever readings are the everyday uses; the 38 °C fever threshold is 100.4 °F.

A temperature difference converts without the offset: a rise of 10 °C is a rise of 18 °F. Rankine is the absolute scale with Fahrenheit-sized degrees, and Réaumur is a historical scale with 80 degrees between the freezing and boiling points of water.

Pertanyaan

How do I convert Celsius to Fahrenheit?

Multiply by 9/5 (1.8) and add 32. For 37 °C, 37 × 1.8 = 66.6, and adding 32 gives 98.6 °F. To go back, subtract 32 and multiply by 5/9: (100 °F − 32) × 5/9 = 37.78 °C. NIST SP 811 states the same relation as t/°F = 1.8 t/°C + 32.

Is 98.6 °F normal body temperature?

98.6 °F is the exact Fahrenheit value of 37 °C, the average Carl Wunderlich published in 1868; individual readings vary with the person, the time of day and where the thermometer goes. For illness the threshold matters more: the NHS treats 38 °C or above as a high temperature, and the US CDC defines fever as 100.4 °F, the same value.

At what temperature are Celsius and Fahrenheit equal?

At −40. Setting the two numbers equal in °F = °C × 9/5 + 32 gives x = 1.8x + 32, so x = −40, and −40 °C is exactly −40 °F. It is the only crossing point because the degrees differ in size; above −40 the Fahrenheit number is always the larger one.

How do I convert Celsius to kelvin?

Add 273.15: 25 °C is 298.15 K, and absolute zero, 0 K, is −273.15 °C. A kelvin is the same size as a Celsius degree and, since 2019, is defined by fixing the Boltzmann constant at 1.380649 × 10⁻²³ J/K (BIPM SI Brochure). Kelvin is written without a degree sign.

Why is a 10 °C rise an 18 °F rise and not 50 °F?

Because a difference has no zero point to shift. One Celsius degree is 1.8 Fahrenheit degrees, so a change of 10 °C is a change of 18 °F; the +32 applies only to a reading on the scale. The converter's steps show the offset and the per-degree factor separately for this reason.

Seberapa akurat “Konverter suhu”?

Akurasi bergantung pada masukan dan asumsi metode. Aritmetika desimal memakai 50 digit signifikan, tetapi perkiraan, metode numerik dan data sumber bisa kurang presisi; pembulatan yang ditampilkan tidak menghilangkan batasan itu. Contoh penyelesaian yang diperiksa dengan sumber independen: 5. Misalnya, “Body temperature, 37 °C in °F” diperiksa dengan °F = °C × 9/5 + 32 (NIST SP 811 §4.2.1.1): 37 × 1.8 + 32 = 98.6.

Dari mana metode ini berasal?

NIST SP 811 (2008), Guide for the Use of the SI, Appendix B — conversion factors; NIST Handbook 44, Appendix C — General tables of units of measurement; BIPM SI Brochure, 9th edition (2019), §2.3.1 — the kelvin and degree Celsius.
