To convert from deciliters (dL) to liters (L), we use the conversion factor that 1 dL = 0.1 L. Therefore, to convert 4 dL to liters:
\[
4 \, \text{dL} = 4 \times 0.1 \, \text{L} = 0.4 \, \text{L}
\]
To convert from kiloseconds (ks) to seconds (s), we use the conversion factor that 1 ks = 1000 s. Therefore, to convert 7000 s to kiloseconds:
\[
7000 \, \text{s} = \frac{7000}{1000} \, \text{ks} = 7 \, \text{ks}
\]
To convert from millimeters (mm) to meters (m), we use the conversion factor that 1 mm = 0.001 m. Therefore, to convert 6000 mm to meters:
\[
6000 \, \text{mm} = 6000 \times 0.001 \, \text{m} = 6 \, \text{m}
\]
To convert from megagrams (Mg) to grams (g), we use the conversion factor that 1 Mg = 1,000,000 g. Therefore, to convert 4 Mg to grams:
\[
4 \, \text{Mg} = 4 \times 1,000,000 \, \text{g} = 4,000,000 \, \text{g}
\]
- \( \boxed{4 \, \text{dL} = 0.4 \, \text{L}} \)
- \( \boxed{7 \, \text{ks} = 7000 \, \text{s}} \)
- \( \boxed{6000 \, \text{mm} = 6 \, \text{m}} \)
- \( \boxed{4 \, \text{Mg} = 4,000,000 \, \text{g}} \)
