**Metric Prefixes **are “labels” that can be placed in front of base units. Whenever using the metric prefix chart, remember that “1” is associated with the metric prefix.

**Conversion factors needed:**

**1 km (kilometer) = 10 ^{3} m (meters)**

**1 cm (centimeter) = 10 ^{-2} m (meters)**

**km to dm: **

$\mathbf{515}\mathbf{}\overline{)\mathbf{km}}\mathbf{\times}\frac{{\mathbf{10}}^{\mathbf{3}}\mathbf{}\overline{)\mathbf{m}}}{\mathbf{1}\mathbf{}\overline{)\mathbf{km}}}\mathbf{\times}\frac{\mathbf{1}\mathbf{}\mathbf{dm}}{{\mathbf{10}}^{\mathbf{-}\mathbf{1}}\mathbf{}\overline{)\mathbf{m}}}$

Complete the following table:

(a) 1245 kg | 1.245 x 10^{6 }g | 1.245 x 10^{9} mg |

(b) 515 km | _______ dm | ________ cm |

(c) 122.355 s | _______ ms | ________ ks |

(d) 3.345 kJ | _______ J | ________ mJ |

Complete the second row
