How many cubic ft in a microwave that is 15x30x15 3/4?

1.1 (cubic feet) = 1 900.8 cubic inches - that is length x depth x height... could be 1 inch by 1 inch by 1900 inches high (unlikely)... but that would still be 1.1 cu ft... or 12 inches by 12 inches by 13.2 inches... and so on

Just measure the inside dimensions of the unit in inches. Get the length, width and height then use this formula: (L x W x H)/12 = Cubic Feet

Get cubic foot size by multiplying height x width x depth.
Divide that by 1728. If oven is 12 x 12 x 12 then it's exactly 1 cubic ft.
If 6 x 6 x 6 then it's 1/2 cubic ft or. 50 cu ft

Multiply interior's height x width x depth. Ex: lets say 10 inches x 12 inches x 8 inches = 10 x 12 = 120 x 8 = 960. Divide 960 by 1728 (12 x 12 x 12) =. 56 cubic ft( point 56) just a tad more then half cubic ft.

The first two numbers indicate the cubic feet this would be a 1.8 cu ft model

Hi, W/D here.

Here's an easy way to calculate your cubic feet: measure and multiply (in inches) the width X depth X height, then divide by 1728. This will give you cubic feet.
For example, if a microwave measured 18" wide X 18" deep X 12" high, it would be 3888 cubic inches; divided by 1728 (cubic inches in one cubic foot) = 2.25 cu.ft.

Is the cubic foot size of the microwave on the name plate?? It seems that with Emerson the size relates closely to the wattage .. 0.9 cu ft is 900 watts, 1.1 cu ft is 1000 watts .. 0.7 cu ft is 700watts .. That would be the closest info I can get.

In GE microwaves, the first 2 digits of the model number are the cubic footage. 1660 is 1.6 cubic foot, 1540 is 1.5 cubic foot. Take care trying to use the existing hardware, the exact placement of hardware and upper installation screws may vary from year to year or model to model..

IF its over the oven = 1.5 cubic ft.

If you want to calculate the volume of an object and have the answer in cubic feet.

Volume=Length X Width X Height
With the dimensions you give
Volume=12.5in X 37in X 20in
Volume=9250 cubic inches

To convert 9250 cubic inches into cubic feet you need to understand that there are 1728 cubic inches in 1 cubic foot.
L X W X H = 12"X12"X12"=1728 cu in

You then multiply 9250cu in and (1/1728cu ft) Really you are dividing 9250 by 1728.
your answer is 5.35 cubic feet.

12 inches in 1 foot
144 square inches in 1 square foot
1728 cubic inches in 1 cubic foot

to convert you put the unit you want to keep on top of the dividend.
to conver to to feet ( randomly selecting 100 inches)
Example converting 100 inches to feet

100inches X ____1ft____ = (100/12) = 8.3 feet
12inches

or cubic inches to cubic feet
4000 cubic inches to cubic feet

4000cu in X ____1cu ft____ = ( 2.33 cu ft)
1728 cu in

if you notice that the units on top and bottom of the dividend cancel each other out leaving the numerator (top number) as your unit.
it also works in reverse

2.33 cu ft X ___1728 cu in____ = (4000 cu in)
1cu ft
