A water-level measuring device using a gear ratio includes: a water pool filled with a liquid; a plot receiving buoyancy by being floated over a water surface of the liquid filled in the water pool; a cable connected to the plot and extending to the outside of the water pool; a first gear connected with the cable; a second gear connected with the first gear; a weight pendulum connected with the second gear and moving in up and down directions, wherein when a water level of the water pool descends, the weight pendulum ascends due to a weight of the plot, and when the water level of the water pool ascends, the weight pendulum descends due to the buoyancy of the plot.
