Convert the following measurements from meters and centimeters to centimeters: 5m 0cm, 10m 45cm, 6m 90cm, 8m 9cm, 9m 0cm.

$$
5 \text{ m } 0 \text{ cm} = (5 \times 100) \text{ cm} + 0 \text{ cm} = 500 \text{ cm} + 0 \text{ cm} = 500 \text{ cm}
$$
The final answer is $\boxed{500 \text{ cm}}$.

$$
10 \text{ m } 45 \text{ cm} = (10 \times 100) \text{ cm} + 45 \text{ cm} = 1000 \text{ cm} + 45 \text{ cm} = 1045 \text{ cm}
$$
The final answer is $\boxed{1045 \text{ cm}}$.

$$
6 \text{ m } 90 \text{ cm} = (6 \times 100) \text{ cm} + 90 \text{ cm} = 600 \text{ cm} + 90 \text{ cm} = 690 \text{ cm}
$$
The final answer is $\boxed{690 \text{ cm}}$.

$$
8 \text{ m } 9 \text{ cm} = (8 \times 100) \text{ cm} + 9 \text{ cm} = 800 \text{ cm} + 9 \text{ cm} = 809 \text{ cm}
$$
The final answer is $\boxed{809 \text{ cm}}$.

$$
9 \text{ m } 0 \text{ cm} = (9 \times 100) \text{ cm} + 0 \text{ cm} = 900 \text{ cm} + 0 \text{ cm} = 900 \text{ cm}
$$
The final answer is $\boxed{900 \text{ cm}}$.

$$
12 \text{ m } 99 \text{ cm} = (12 \times 100) \text{ cm} + 99 \text{ cm} = 1200 \text{ cm} + 99 \text{ cm} = 1299 \text{ cm}
$$
The final answer is $\boxed{1299 \text{ cm}}$.

$$
3 \text{ m } 16 \text{ cm} = (3 \times 100) \text{ cm} + 16 \text{ cm} = 300 \text{ cm} + 16 \text{ cm} = 316 \text{ cm}
$$
The final answer is $\boxed{316 \text{ cm}}$.

$$
5 \text{ m } 62 \text{ cm} = (5 \times 100) \text{ cm} + 62 \text{ cm} = 500 \text{ cm} + 62 \text{ cm} = 562 \text{ cm}
$$
The final answer is $\boxed{562 \text{ cm}}$.

$$
8 \text{ m } 1 \text{ cm} = (8 \times 100) \text{ cm} + 1 \text{ cm} = 800 \text{ cm} + 1 \text{ cm} = 801 \text{ cm}
$$
The final answer is $\boxed{801 \text{ cm}}$.

$$
8 \text{ m } 99 \text{ cm} = (8 \times 100) \text{ cm} + 99 \text{ cm} = 800 \text{ cm} + 99 \text{ cm} = 899 \text{ cm}
$$
The final answer is $\boxed{899 \text{ cm}}$.
