Conversation

Did you know that the weather report mentioned a drop in pressure measured in millibars?

Really? I didn't realize they used that unit for pressure.

Yeah, they said it dropped below a thousand millibars last night.

That's interesting! I guess that explains the stormy weather.

Root Explanation

Millibar is formed from "milli-" (meaning one thousandth) and "bar" (from Greek "baros", meaning weight or pressure). The term millibar refers to a unit of pressure equal to one thousandth of a bar, which is a measure of atmospheric pressure.

Memory Tip

Think of 'milli-' meaning one thousandth, and 'bar' relating to weight or pressure. This helps you remember that a millibar is a small unit of pressure.
