English measures (aka as Imperial measures) and Metric measures.
Measurements are ways that we tell others how much of an item we have. There are two systems of measuring things—English and Metric. English measurements are used in the United States and UK, while metric measurements are used in nearly every other country. Measurements are used to give number values to distance (length, width, and height), weight, time, volume (liquid measurements), and temperature.

Common Metric Measures
The metric system is also divided into different categories of measurement, but it has a base unit for each category. A base unit means that that is what the category is usually (but not always) measured in, and all the other terms of measurement in that category are built from the base unit.
| Distance | ||||||
| Millimeter (mm) | 1000 mm | = | 1 m | |||
| Centimeter (cm) | 100 cm | = | 1 m | |||
| Meter (m) | base unit (1) | |||||
| Kilometer (km) | 1000 m | = | 1 km | |||
| Weight | ||||||
| Milligrams (mg) | 1000 mg | = | 1 g | |||
| Grams (g) | base unit (1) | |||||
| Kilograms (kg) | 1000g | = | 1 kg, | 1000 kg | = | 1 t |
| Metric ton (t) | 1000 kg | = | 1 t | |||
| Volume | ||||||
| Milliliters (mL) | 1000 mL | = | 1 L | |||
| Liters (L) | base unit (1) | |||||
| Temperature | ||||||
| Degrees Celsius (°C) | ||||||
| Speed | ||||||
| Meters per second (m/s) |
****Note that centimetre, metre, litre are also posible spellings.
