The formula to calculate the Candle Burn Time (BT) is:
\[ BT = \frac{W}{BR} \]
Where:
Let's say the weight of the candle is 200 grams and the burn rate is 10 grams per hour. Using the formula:
\[ BT = \frac{200}{10} \]
We get:
\[ BT = 20 \text{ hours} \]
So, the candle burn time is approximately 20 hours.
