1000 liters A cubic metre is equivalent to 1,000 litres of water. This translates to 28 showers or 13 baths.

The water meter keeps track of how much water you consume in cubic meters (m3). One cubic metre is equivalent to 1000 litres, which is enough for 13 baths, 14 washing machine loads, 28 showers, 33 dishwasher loads, or 111 toilet flushes!

Washing machines come in all sizes from **small washer units** that fit into a cupboard to large models that can be placed in the basement. The amount of water used by **a washing machine** depends on several factors such as type of fabric, temperature, amount of stain, etc. For example, if you wash your clothes in hot water then you will use more energy than if you wash them at **cold temperature**.

Washers use between 1 and 2 kilowatts (kW) when running at full speed, depending on their size. They use even more power when they spin dry your clothes because the motors need to run continuously while the washer is spinning at high speed.

A washing machine uses about 20-50 watts (W) when it is standing by itself and this number may increase to **over 100 W** when it is also washing dishes or doing other things at the same time. A household using an air conditioner uses an average of 1500-2500 W during operation. Thus, having both a washing machine and an air conditioner working at the same time can have an impact on the energy usage and costs of your household.

1 cubic metre equals 1000 litres.

The volume of gasoline in a gallon is approximately 0.9 litres, so 10 gallons of gasoline will fill a 13-gallon tank. A diesel engine needs about 1.8 litres of oil per mile, so 6 miles per gallon would require **a diesel engine** that can handle 18-ounces (oz) per mile.

A standard gas tank holds 9 oz, and some large trucks have tanks with volumes as high as 20 oz per full tank. At **one dollar** per gallon, this means that the cost of filling the largest possible tank is only $18. It takes more than one million barrels of oil to make one million gallons of gasoline, so the average price of oil must be at least one dollar per gallon to justify the production of such a large quantity of gasoline.

The number of cars in **the United States** has increased by more than 50 percent since 1996, when there were just under 16 million vehicles on the road. If the average size of those cars was taken into account, then it could be argued that the need for **gasoline increases** proportionally to the number of vehicles on the road.

80 liters A full bath may consume up to 80 litres of water, whilst a five-minute power shower consumes around 75 litres. If you average these figures over a month they amount to about 678 millilitres (25 inches) or 2 pints.

The water consumed by your home comes from **several sources**: the groundwater that flows into your house through **porous soil** containing many holes called pores; the surface water such as lakes and rivers; and the deep underground water known as groundwater. The amount of water that can be taken from **each source** is called its capacity. For example, the capacity of the groundwater is estimated to be 740 million litres (175 gallons), while the capacity of the lake is 30 million litres (7000 gallons). Your household uses about 1% of the lake's capacity but 10% of the groundwater's capacity.

Groundwater is drawn up through soil pores using the same process as drinking water except that some of the water soaks into the rock instead of coming out of the ground. As it travels through the rock, salt is left in the soil because there is no outlet for it to go back into the groundwater system. This is called "saltwater intrusion".

This will give you **the cubic metres** (m3), which you can then multiply by 1000 to get the litres. For instance, 1.8m x 0.6m x 0.7m equals 0.76m3 and 0.76m3 x 1000 equals 760 litres.

There are 2.2 million m3 in **a million ft3**. Multiply this by 7.5 to find the volume of water that would fill a million ft3: 20,000,000 ml = 20,000 gal or 960,000 liters.

A million ft3 is about 2 acres. So, it takes about 92,000 gallons of water to cover one acre in grass.

The amount of water in **90,000 gal** is about 19,500 ml. That's less than one half of a barrel or 5.9 m3. A barrel contains 42 liters, so one half of a barrel is 23.7 m3.

Here are two other ways to calculate the volume of water in 1.8 million cubic feet: First, divide the number by 12 to find out how much each cubic foot represents. Then, multiply that by **the total volume** to find out the number of barrels required. In this case, it's 925 barrels.
