The formula to convert beats per minute to milliseconds is:
\[ ms = \frac{60000}{BPM} \times T \]
Where:
BPM to MS stands for beats per minute to milliseconds. The conversion is done through the use of tempo.
Let's assume the following values:
Step 1: Calculate the milliseconds (ms):
\[ ms = \frac{60000}{120} \times 1 = 500 \text{ ms} \]
The milliseconds for a quarter note at 120 BPM is 500 ms.
