To convert from Celsius to Kelvin, we add 273. So, 50°C + 273 = 323 K.

To convert from Kelvin to Celsius, we subtract 273. So, 300 K - 273 = 27°C.

To convert from Fahrenheit to Celsius, we use the formula: °C = (°F - 32) × 5/9. So, (-40 - 32) × 5/9 = -40°C.

To convert from Celsius to Fahrenheit, we use the formula: °F = (°C × 9/5) + 32. So, (25 × 9/5) + 32 = 77°F.

To convert from Kelvin to Celsius, we subtract 273. So, 373 K - 273 = 100°C.

To convert from Celsius to Fahrenheit, we use the formula: °F = (°C × 9/5) + 32. So, (100 × 9/5) + 32 = 212°F.

To convert from Celsius to Kelvin, we add 273. So, 20°C + 273 = 293 K.

To convert from Fahrenheit to Celsius, we use the formula: °C = (°F - 32) × 5/9. So, (-10 - 32) × 5/9 = -23.33°C.

To convert from Celsius to Kelvin, we add 273. So, 25°C + 273 = 298 K.

To convert from Celsius to Fahrenheit, we use the formula: °F = (°C × 9/5) + 32. So, (0 × 9/5) + 32 = 32°F.
