Question

457 centigrams
minute
=

milligrams
hour

Answer 1

To convert 457 centigrams per minute to milligrams per hour, we can follow these steps:

1. **Convert centigrams to milligrams**:
- 1 centigram (cg) = 10 milligrams (mg)
- Therefore, 457 centigrams = 457 × 10 mg = 4570 mg.

2. **Convert minutes to hours**:
- There are 60 minutes in an hour.

3. **Calculate milligrams per hour**:
- If you have 4570 mg per minute, then for one hour (60 minutes), you multiply by 60.
- 4570 mg/min × 60 min/hour = 274200 mg/hour.

So,
\[ 457 \text{ centigrams per minute} = 274200 \text{ milligrams per hour} \]
