36000 btu per hour to tr conversion result above is displayed in three different forms: as a decimal (which could be rounded), in scientific notation (scientific form, standard index form or standard form in the United Kingdom) and as a fraction (exact result). Every display form has its own advantages and in different situations particular form is more convenient than another. For example usage of scientific notation when working with big numbers is recommended due to easier reading and comprehension. Usage of fractions is recommended when more precision is needed.
If we want to calculate how many Tons of Refrigeration are 36000 BTUs per Hour we have to multiply 36000 by 1 and divide the product by 12000. So for 36000 we have: (36000 × 1) ÷ 12000 = 36000 ÷ 12000 = 3 Tons of Refrigeration
So finally 36000 btu per hour = 3 tr
