Temperature Conversion Calculator

Instantly convert any time unit with precision.

Converting temperatures among various scales can be challenging. Our interactive Temperature Conversion Calculator not only performs accurate conversions among eight different temperature units but also shows you each arithmetic step with unit-specific annotations. Whether you’re a student, an educator, or a professional needing quick and precise conversions, this tool is designed to help you learn and work more efficiently.

How the Calculator Works

The calculator operates in two phases:

1. Convert to Celsius (Intermediate Step):
   Regardless of your input unit, the value is first converted to Celsius using its dedicated formula. This step standardizes the conversion process.
2. Convert from Celsius to Your Desired Unit:
   If your target unit is not Celsius, the calculator then converts the Celsius value into the target unit using the corresponding formula.

Both steps display the full arithmetic expression with unit symbols for clarity.

Conversion Formulas

1. Converting to Celsius

The following table summarizes the formulas used to convert different temperature units to Celsius:

Conversion	Formula	Example
Fahrenheit → Celsius	(F – 32) × 5/9	(50°F – 32) × 5/9 = 10.00°C
Kelvin → Celsius	K – 273.15	300K – 273.15 = 26.85°C
Rankine → Celsius	(R – 491.67) × 5/9	(600°R – 491.67) × 5/9 ≈ 60.00°C (example value)
Delisle → Celsius	100 – (D × 2/3)	100 – (20°D × 2/3) = 100 – 13.33 ≈ 86.67°C
Newton → Celsius	N × 100/33	10°N × 100/33 ≈ 30.30°C
Réaumur → Celsius	Re × 5/4	20°Ré × 5/4 = 25.00°C
Rømer → Celsius	(Ro – 7.5) × 40/21	(18°Rø – 7.5) × 40/21 ≈ 20.95°C
Celsius → Celsius	Value remains the same	25°C remains 25°C

2. Converting from Celsius to the Target Unit

After obtaining the Celsius value, the conversion to the target unit is done using these formulas:

Conversion	Formula	Example
Celsius → Fahrenheit	(C × 9/5) + 32	(10°C × 9/5) + 32 = 50.00°F
Celsius → Kelvin	C + 273.15	26.85°C + 273.15 = 300K
Celsius → Rankine	(C + 273.15) × 9/5	(10°C + 273.15) × 9/5 ≈ 527.67°R
Celsius → Delisle	(100 – C) × 3/2	(100 – 25°C) × 3/2 = 112.50°D
Celsius → Newton	C × 33/100	30°C × 33/100 = 9.90°N
Celsius → Réaumur	C × 4/5	25°C × 4/5 = 20.00°Ré
Celsius → Rømer	(C × 21/40) + 7.5	(20°C × 21/40) + 7.5 ≈ 16.75°Rø
Celsius → Celsius	Value remains the same	25°C remains 25°C
