Explanation:

Step1: 单位统一，比较18题

因为$1\ \text{L}=1000\ \text{mL}$，所以$1.5\ \text{L}=1.5\times1000=1500\ \text{mL}$，即$1500\ \text{mL}=1.5\ \text{L}$

Step2: 单位统一，比较19题

因为$1\ \text{dm}=10\ \text{cm}$，所以$53.6\ \text{dm}=53.6\times10=536\ \text{cm}$，即$536\ \text{cm}=53.6\ \text{dm}$

Step3: 单位统一，比较20题

因为$1\ \text{g}=1000\ \text{mg}$，所以$5\ \text{g}=5\times1000=5000\ \text{mg}$，$43\ \text{mg}<5000\ \text{mg}$，即$43\ \text{mg}<5\ \text{g}$

Step4: 单位统一，比较21题

因为$1\ \text{m}=100\ \text{cm}$，所以$3.6\ \text{m}=3.6\times100=360\ \text{cm}$，$360\ \text{cm}>36\ \text{cm}$，即$3.6\ \text{m}>36\ \text{cm}$

Answer:

1. $1500\ \text{mL} = 1.5\ \text{L}$
2. $536\ \text{cm} = 53.6\ \text{dm}$
3. $43\ \text{mg} < 5\ \text{g}$
4. $3.6\ \text{m} > 36\ \text{cm}$
