To convert BTUs to tons, find the BTU capacity of the air conditioner, and divide the BTUs by 12,000. Twelve thousand BTUs equals the amount of heat removed by an air conditioner that would melt 1 ton of ice in 24 hours, which is called the chiller refrigeration ton, according to The Engineering Toolbox.
On the tag or packaging, find the BTU rating of the air conditioner. The number is expressed in thousands, such as 6,000 BTU or 15,000 BTU.
Using a calculator, divide the unit's BTU rating by 12,000 to arrive at the chiller refrigeration ton capacity. The equation may yield a fraction. For instance, a 6,000-BTU window air conditioner equals 1/2 ton of cooling capacity.
An old rule of thumb stipulated that 1 ton of air conditioning should cool 400 square feet of living space. However, many air conditioners are too large for the site, which results in high humidity and wasted energy. The current thinking, according to Green Building Advisor, is 1 ton per 1,000 square feet of space, with some adjustments based on ceiling height, climate, number of windows and other variables.
To convert board-feet to tons, use the conversion factor of one board-foot to one ton which, is 0.0023172750963701. Multiply this number with any volume in board-feet, and you will get the weight in tons. For example, if you have 10,000 board-feet of lumber, the equivalent weight in tons is 23.17 tons, rounded off to two decimals.Full Answer >
There are 3.517 kilowatts in a ton of refrigeration, so in order to convert kW to tons, divide the number of kW by 3.517. One ton of refrigeration is approximately 12,000 BTUs, or British thermal units, which is the rating system of air conditioning units in many English-speaking countries outside of the United States.Full Answer >
Cubic meters, which measure volume, are converted to tons, which measure mass, by multiplying the number of cubic meters of a substance by its density in units of cubic meters per ton. Density is a physical property defined as the mass of a substance per unit volume.Full Answer >
Metric tons of crude oil can be converted to barrels by multiplying total tonnage by 7.33. The conversion rate for crude oil is an approximation because it is based on the worldwide average gravity of crude oil. Refined oil products have a variety of conversion factors due to density variations.Full Answer >
