You can use that for troubleshooting your efficiency, 1 full can is 1 inch irrigation/rainfall. Two weather stations with some distance between them can often give very different measurements. Total rainfall is still measured from 0900 to the next day at 0900. But now the measurements are fully automatic, https://www.bookstime.com/ so the meteorological service gets the data more often and can provide data for each hour of the day. To avoid confusion, use any and all abbreviations consistently throughout all your financial records. Please provide values below to convert millimeter [mm] to inch [in], or vice versa.

## Convert Millimeter to Meter

1M typically represents one million, while 1MM can either represent one million or one thousand depending on the context. It is important to clarify the unit of measure when using these abbreviations to avoid confusion. This one goes up to 12 cm or 120 mm, so 3 mm would just be a few drops at the bottom. And it’s still true that a storm that affects a larger area with 3mm of rainfall does put down more total water quantity in entirety. If the same storm hits all of China, that’s indeed a lot of water!

## How to convert millimeters to inches

This means that millimeters are used when measuring small distances or dimensions such as the thickness of a sheet of paper or a small object. To make the conversion easier, you can what does mm mean use the millimeters to inches conversion calculator provided on this page. This tool will calculatate the value for you and also give the result in fractional form if required.

## Millimeter and Other Customary Units

It is a small unit of measurement compared to the centimeter, meter, inches, and feet we are familiar with. A surface of 10 square meters was also filled with water up to a height of 3mm, etc. If a financial statement has a lot of large figures, the accountant may simply dispense with abbreviations. Stating at the top of the report that “all figures are in millions of dollars” should take care of it. What matters is that readers look at the figures and understand the amounts.

- Inches are commonly used in the United States and the United Kingdom.
- Millimeter is used for measuring small lengths and visible distances.
- So if the storm hit the entirety of Hong Kong as it hit the airport, the rain gauge at that airport would record 3mm, and so would any other rain gauge in the city.

However, our abbreviations are a concoction of multiple cultural legacies ranging from Rome, Greece, India, China, and Arabia. If 1,000 multiplied by 1,000 equals 1,000,000, and 1,000 equals M, then we can use the abbreviations to create calculations. Within finance and accounting, we often find something quite different. For example, a thousand is often abbreviated as (M), a million is abbreviated as (MM), and a billion is abbreviated as (BN) or (MMM).
