Fox News hosts like Tucker Carlson depend on frightening their viewers for ratings.

But using the metric system to fear monger...really Tucker? That's nutty, even for Fox News.

Carlson's show warned viewers about vague powers of "global revolution and new world order" that promote the menacing metric system. Crackpot guest James Pinero, went on to claim the metric system (widely used outside of the U.S) is linked to radicalism, revolution, and a "globe that is not even accurate."

We're all dumber after hearing Carlson and Pinero weigh in on the metric system.

If you're terrified of units of measurement and generally hopeless with numbers, here's a quick refresher on the metric system, via InterExchange.

"There are two main systems for measuring distances and weight, the Imperial System of Measurement and the Metric System of Measurement."

"Most countries use the Metric System, which uses the measuring units such as meters and grams and adds prefixes like kilo, milli and centi to count orders of magnitude."

"In the United States, we use the older Imperial system, where things are measured in feet, inches and pounds."

Hearing Tucker and Pinero's brain melting conspiracy theories, you'd think the metric system was some evil sorcery.

"We should stand tall on our own 2 feet, I say. Because it is customary measures that measured out the revolution and customary measures that took us to the moon."

"The metric system meanwhile is the product of the French revolution. It was imposed at the business end of the guillotine."

Regrettably, Tucker asked his guest for more details...

'"So why are our leaders so anxious that we join the rest of the world in using Robespierre's favorite standard of measurement, I don't understand?"

But the more Pinero went on the less it made sense.

"All customary measures use man and his labour as the basis of the measurement."

"What is an acre? It is the land that an ox and can till in one day. 5,000 paces, a pace of 5,000 feet each."

"A meter is what? The globe that is not even accurate."

People on Twitter also found the exchange confusing.

Carlson railed against the "made-up" metric system, apparently forgetting all numerical systems are literally made-up.

Some noticed Tucker couldn't even pronounce 'kilograms' properly.

A couple people flexed their math skills to clown on Tucker.

Others found darker meaning in the Fox host's rant against the metric system.

But mostly, people just laughed at the lowly dumpster fire that is Fox News.

You know what? Forget the metric system...

I'd rather Fox News viewers convert to a different channel.
