Mark the statements which are correct.

(Select all that apply.)

106 mm = 1014 pm
106 mg = 1012 ng
1 s = 103 ms
10-3 g = 1012 ng
1 mg = 103 μg

Let's analyze each statement one by one to determine which are correct. 

### Analyzing Each Statement:

1. **106 mm = 1014 pm**

   To check this, we need to convert millimeters (mm) to picometers (pm):
   
   \[
   1 \, \text{mm} = 10^6 \, \text{pm}
   \]

   Therefore,

   \[
   106 \, \text{mm} = 106 \times 10^6 \, \text{pm} = 10^8 \, \text{pm}
   \]

   So, this statement is **incorrect** because \( 10^8 \neq 10^{14} \).

2. **106 mg = 1012 ng**

   To verify this, we need to convert milligrams (mg) to nanograms (ng):

   \[
   1 \, \text{mg} = 10^6 \, \text{ng}
   \]

   Therefore,

   \[
   106 \, \text{mg} = 106 \times 10^6 \, \text{ng} = 10^8 \, \text{ng}
   \]

   This statement is **incorrect** because \( 10^8 \neq 10^{12} \).

3. **1 s = 103 ms**

   To check this, we convert seconds (s) to milliseconds (ms):

   \[
   1 \, \text{s} = 10^3 \, \text{ms}
   \]

   This statement is **correct**.

4. **10^-3 g = 1012 ng**

   To check this, we convert grams (g) to nanograms (ng):

   \[
   1 \, \text{g} = 10^9 \, \text{ng}
   \]

   Therefore,

   \[
   10^{-3} \, \text{g} = 10^{-3} \times 10^9 \, \text{ng} = 10^6 \, \text{ng}
   \]

   This statement is **incorrect** because \( 10^6 \neq 10^{12} \).

5. **1 mg = 103 μg**

   To check this, we convert milligrams (mg) to micrograms (μg):

   \[
   1 \, \text{mg} = 10^3 \, \text{μg}
   \]

   This statement is **correct**.

### Conclusion:

The correct statements are:

- **3. 1 s = 103 ms**
- **5. 1 mg = 103 μg**
