What does Btu (th) foot/hour/sq. foot/°F measure?

It measures the rate of heat transfer through a material in imperial units, indicating how many Btu per hour pass through a one-foot thickness with a one square-foot area for a 1 °F temperature difference.

What is kilocalorie (IT)/hour/meter/°C used for?

This unit expresses thermal conductivity in terms of heat flow in kilocalories per hour through a one-meter thickness at a 1 °C temperature difference, commonly used in non-SI and international engineering contexts.

Why is precise conversion between these units important?

Because they are based on different systems and temperature scales, precise conversions ensure accurate heat transfer and energy loss calculations critical in engineering and building design.
