What is the formula to convert Celsius to Fahrenheit?

°F = (°C $\times$ 9/5) + 32. For example, 25°C = 77°F.

What is the formula to convert Celsius to Kelvin?

K = °C + 273.15. For example, 25°C = 298.15 K. Kelvin uses the same increment size as Celsius.

Why is Kelvin used in science?

Kelvin is an absolute temperature scale starting at absolute zero (0 K = -273.15°C), making it essential for thermodynamic calculations, gas laws, and physical chemistry.

What temperature scales are used in aquaculture?

Most aquaculture literature uses Celsius. Fahrenheit is common in US practice. Kelvin is rarely used in aquaculture but is standard in thermodynamic calculations.

Celsius and Kelvin have the same increment

A 1°C change equals a 1 K change. Only the zero point differs (0°C = 273.15 K).

Fahrenheit increments are smaller

A 1°F change is only 5/9 of a 1°C change. This means Fahrenheit provides finer granularity without decimals.

Method

Standard SI temperature conversion formulas. Celsius is the base unit; Fahrenheit and Kelvin are derived from it.
