Calculate the weight of a 12 kg bag of kaukau and convert 25°C to Fahrenheit.

The formula for weight ($W$) is mass ($m$) multiplied by the acceleration due to gravity ($g$). On Earth, $g \approx 9.8 \, \text{N/kg}$.

$$W = m \times g$$

Given mass $m = 12 \, \text{kg}$.

$$W = 12 \, \text{kg} \times 9.8 \, \text{N/kg}$$

$$W = 117.6 \, \text{N}$$

The weight of the bag of kaukau is $\boxed{\text{117.6 N}}$.

The formula to convert temperature from Celsius ($C$) to Fahrenheit ($F$) is:

$$F = C \times \frac{9}{5} + 32$$

Given temperature $C = 25^\circ\text{C}$.

$$F = 25 \times \frac{9}{5} + 32$$

$$F = (25 \div 5) \times 9 + 32$$ $$F = 5 \times 9 + 32$$ $$F = 45 + 32$$ $$F = 77^\circ\text{F}$$

$25^\circ\text{C}$ is equal to $\boxed{\text{77}^\circ\text{F}}$.
