 milligrams

To calculate the usual dose of Ibuprofen for a child based on weight, we can follow these steps:

1. **Convert the child's weight from pounds to kilograms**:
   - 1 kilogram (kg) = 2.2 pounds (lbs).
   - The child weighs 25 pounds.

   \[
   \text{Weight in kilograms} = \frac{25 \, \text{lbs}}{2.2} = 11.36 \, \text{kg}
   \]

2. **Calculate the dose in milligrams (mg)**:
   - The usual dose is 5 mg per kg of body weight.
   
   \[
   \text{Dose} = 5 \, \text{mg} \times 11.36 \, \text{kg} = 56.8 \, \text{mg}
   \]

3. **Round to the nearest milligram**:
   \[
   56.8 \, \text{mg} \approx 57 \, \text{mg}
   \]

So, the usual dose of Ibuprofen for the child is **57 milligrams**.
