This is the volume of the rectangular shape which corresponds to the dimensions entered for length, width and height. thousandth of an inch (thou) – 0.0000254 m.The following SI unit conversion factors in metres (m) are used for converting the measurement units specified for length, width and height: SI Metric Prefix Length Units Volume Dimensions – Length, Width & HeightĮnter the measurement of length, width and height for the rectangular shape. The formula used by this calculator to calculate the volume of a rectangular shaped object is: Also a graphic will be shown of a scaled 3D drawing to the correct proportions and labelled with each dimension and calculated volume. Once the measurements have been entered for length, width and height, the calculated volume will be shown in the answer box. There is no need to input values in the same measurement units, just select your preferred units for each dimension and calculated volume. This online tool calculates the volume of a rectangular shaped box, solid or space from the dimensions of length, width and height.

Kitchens normally have more heat thanks to stoves and ovens, and rooms with computers and other electronics give off extra heat.
Other factors in determining the BTU size would be the room’s purpose.
If the room has more windows, doors or higher ceilings, adjust the BTUs upward. These BTU calculations are based on a standard room with 8-foot ceilings, two windows and one door. The chart below is a great starting point for sizing your AC. Many factors go into calculating BTUs, so we have put together a set of tools to help with air conditioner sizing. That might not sound useful when it comes to air conditioning your home or business but the underlying calculation is critical to staying comfortable.Įach air conditioner or heater is rated to produce a certain number of BTUs. What is a BTU?Ī BTU or British Thermal Unit is a measurement of how much energy is required to raise the temperature of one pound of water by one degree. Here’s how to calculate BTU to find the perfect AC unit for your needs. On the other hand, too large a unit for the space will not remove the necessary moisture from the room, making it feel clammy and uncomfortable. Choose too small a unit, you could end up with a room that's not cool enough, or with an air conditioning unit that overheats. Especially when choosing the correct BTU size for an air conditioner.
