The volume of all fresh water on Earth would be about 8 to 10 million cubic miles. That sounds like a lot except that 2/3 of that is frozen into glaciers and the ice caps in Greenland and Antarctica.
-----
Estimates vary on the percent of the Earth's water that is fresh, but it is only about 2.5 to 3% of the Earth's water. Most of this fresh water is frozen in the ice caps (Greenland and Antarctica) and in glaciers.
NASA says Earth's total water content is about 1.39 billion cubic kilometers (331 million cubic miles) and that 2.5% of that is fresh water. (And 68.9% of it is locked up in glaciers) The US Geological Survey says that up to 3% of the world's water is fresh.

Fresh water reserves constitute about 2.5-2.75% of the total water on Earth.
Approximately 0.3% of the Earth's total water supply is fresh liquid water available for human consumption and use. This freshwater is found in rivers, lakes, and groundwater sources. The majority of Earth's water is saline and found in oceans and seas.
Roughly 97.5% of Earth's water is salt water, found in the oceans, while about 2.5% is fresh water. Most of the fresh water is locked up in ice caps and glaciers, with a small fraction available in rivers, lakes, and groundwater.
Most of Earth's fresh water is stored in glaciers and ice caps, accounting for about 68.7% of the total fresh water. Other sources include groundwater, which makes up about 30.1%, and surface water in lakes, rivers, and swamps, which account for roughly 0.3%.
Around 69% of Earth's fresh water is stored in glaciers.
About 2.59% of Earth's total water supplies is drinkable water
The total volume of water on Earth is estimated at 1.386 billion km³ (333 million cubic miles). About 97.5% of water on Earth is salt water and 2.5% fresh water. Of the 2.5% fresh water, only 0.3% is in liquid form on the surface.
Fresh water reserves constitute about 2.5-2.75% of the total water on Earth.
The total volume of water on Earth is less than 1,500 million km3. The overall volume of the Earth is 1,100,000 million km3. The percentage of water by volume is therefore about 0.1%This is by comparison a much smaller percentage of water than is found on Europa
Fresh water in frozen glaciers and ice caps accounts for about 69% of the total amount of fresh water on earth.
3% of Earth's water is fresh and of this 3%, 69% is Ice.Thus 97% of Earth's water is saltyand 2.07 of the fresh water is Ice.Which means 99.07% of Earth's water is not liquid fresh water.__________________________________________________________________The percentage of fresh water volume to total water is 2.5 %.Of this total volume 70% is ice.Of this fresh water around 30% is underground water.Fresh water lakes and rivers contain around 0.3% of total fresh water.The total usable fresh water is less than 1% of all fresh water resources.refer to link below
The Earth's total surface is 80% water and only 2.5% is fresh water.
2.7%
The Earth's total amount of water has a volume of about 344 million cubic miles. 97% or 333.68 million cubic miles of this is seawater. Of the 3% or 10.32 million cubic miles left as fresh water, some 2% or 6.88 million cubic miles of the total is frozen.
685,767,231 mi3
The density of ice is about 0.917 of that of fresh water.Essentially all the world's ice is locked up in the Antarctic, and it is likewise essentially the total volume of fresh water on Earth.It is ~ 3 - 4 % of the Earths total water, of which most is in the Oceans.The volume of the Oceans is about 1.3x109km3. So 3 or 4 % of that volume is the volume of earth's ice. I'm sure your calculator can handle the calculation.It is not worth making the correction for the manner in which ice expands when it freezes, for the numbers are necessarily approximate.
The total volume of water on earth is 1.3 billion cubic kilometers. This is equal to 310 million cubic miles.total weight of water on earth is 1.4x1021kg.1 kg is approx equal to 1L of water,so approx 1.4x1021L of water.
