Therefore, it is important to understand US Customary and Imperial Units and how they convert to metric units.
US Customary/Imperial Unit Equivalent SI unit (metric).
1 inch (inch) 25.4 millimeters (mm)
1 in 2.54 centimeters (cm)
1 foot (ft) 30.48 cm
1 yard (yd) 0.91 meter (m)

In the United States, SI is used in medical, scientific, and many other specialized technical works. However, for business and daily life, we usually use the system called “US Customary”.
1 answer. There are several reasons why SI is preferred to Old English measurement: SI is not based on the arbitrary construct of the human body; rather according to precise and clear standards. SI uses base 10, just like our number system, so it’s much easier to learn, remember, and convert between units.
The two most commonly used units of power in US units are mechanical horsepower and BTU/hour. The watt, a metric SI unit of power, is also widely used. Boiler output is the rate of energy required to vaporize 34.5 lb (15.65 kg) of water at 212°F (100°C) in one hour.
To convert from a larger unit to a smaller one, multiply. To convert from a smaller unit to a larger one, divide.
The only difference between the imperial system and the US system is the volume measurement. Not only are the number of ounces in pints, quarts, and gallons all larger in the imperial system, the size of a fluid ounce is also different, as shown in the chart in Table 7. 1 (liquid) ounce.
US units of weight are ounces, pounds and tons. The US units of measurement for capacity or volume are ounces, cups, pints, quarts, and gallons. – The usual system is called the International System of Units or Modern Metric System.
The biggest advantage of SI is that there is only one unit for each quantity (measurement type). This means there is never a need to convert from one unit to another (within the system) and there are no conversion factors for students to remember. For example, the only SI unit of length is meter (m).
An easy way to convert numbers to scientific notation is to shift the decimal point left or right to make a number from 1 to 10 (N). The size of n is then determined as follows: if the decimal point is shifted n places to the left, n is positive.
