A microgram (mcg) is a unit of mass equal to one-millionth of a gram.
While the official symbol for the microgram in the International System of Units (SI) is μg (using the Greek letter Mu), you'll often see it written as mcg.
This is particularly common in the medical and pharmaceutical fields.
Using 'mcg' is a crucial safety measure to prevent dosage errors. A handwritten 'μg' could easily be mistaken for 'mg' (milligram), which would result in a 1,000-times overdose—a potentially fatal mistake.
The microgram is the go-to unit for measuring very potent substances, where tiny differences matter for both safety and effectiveness.
It's used for specific substances like:
Measuring in micrograms makes it possible to give an effective dose without risking toxicity.
It's hard to picture how tiny a microgram is.
For perspective, a single grain of ordinary table salt weighs about 500–600 micrograms — meaning a single grain contains more than 500 micrograms.
That helps explain why we measure very potent substances in micrograms: their active doses are tiny.
A metric tonne, often called simply a tonne (symbol: t), is a standard unit of mass in the metric system.
It's commonly used around the world to measure heavy objects, especially in trade and industry.
So, how heavy is it?
It's also equivalent to one million grams (106 g), which is why it's sometimes called a megagram (Mg).
A great way to visualize a metric tonne is to think of a cube of water.
Imagine a cube that's one meter on each side—one meter tall, one meter wide, and one meter long. If you were to fill that cube with pure water, its mass would be exactly one metric tonne (1,000 kilograms).
This simple and direct relationship between volume (1 m3) and mass (1 tonne) is a perfect example of what makes the metric system so logical and practical.
The term "ton" can be confusing, as it refers to different units of weight depending on the location.
Understanding this distinction is crucial, especially in the context of international shipping.
Key takeaway: A US short ton is roughly 10% lighter than a metric tonne, whereas a UK long ton is slightly heavier. Always specify the unit to prevent costly errors!
