🔍 Key Concepts

• refrigeration ton as a unit of cooling capacity • the standard BTU per hour value for one ton of refrigeration • basic ratio / unit conversion from BTU/hr to tons

💭 Think About

• First, recall or look up how many BTU per hour are in one ton of refrigeration. • Then, set up a simple division to convert 48,000 BTU/hr into tons using that standard value. • Compare your result with the multiple-choice options and decide which is closest to your calculated value.

✅ Before You Answer

• Be sure you are using BTU per hour, not per minute or per day. • Double-check the standard value you use for 1 ton of refrigeration (BTU/hr) before doing the math. • Recalculate the division once more to confirm you didn’t misplace a zero or decimal point.
