Mach Speed
Sound Speed Value
Enter the Mach number, (speed of sound multiple), or any other sound speed value that you want to convert. For example, enter 1.0 for Mach 1 (the speed of sound), enter 0.1 for Mach 0.1 (one tenth the speed of sound), and enter 2.0 for Mach 2 (twice the speed of sound). Your input should be in one of these formats: Integer: 2 Decimal: 2.71 Scientific Notation: 0.352e02 Formula: (2.7*5e2)/( 1 + (6.5/1.8e-2) ) Fraction: 9 + ( 17 / 32 ) Calculator Memory: You can use the results from previous conversions or calculations, which you may have saved in the Calculator Memory. First set focus on the sound speed input field, then click the Recall button on one of the Memories. The memory contents is loaded to the input field. See the Calculator Memory for more details. Maximum Input Length: 200 charactersFrom and To Menus
From Menu In this menu, choose the altitude, in the International Standard Atmosphere (ISA), at which your sound is traveling, or the units of the sound speed value you entered, for example one of these. mach (3000 feet ISA) mach (18000 feet ISA) mach (30000 feet ISA) kilometers per hour miles per hour feet per second To Menu In this menu, choose the sound speed units you want to convert to, or choose an altitude for the Mach number of your result. For example, choose one of these. meters per second miles per hour kilometers per hour mach (60000 feet ISA) mach (15000 feet ISA) mach (6000 feet ISA)
TIP:
Drag your mouse pointer in the To or From menu to change units. Release the mouse button to perform a new conversion.
TIP:
Select units in the To or From menu. Press the Up and Down arrow keys on the keyboard to change units and do a new conversion.
Sound Speed Value You Entered
The sound speed value you entered in the input field, is shown here again as a number with the From units added. If you entered a formula or a fraction in the sound speed input field, your formula or fraction was calculated and reduced to this number. The units shown here are the units selected in the From menu. TIP:
You can Copy and Paste any of the fields by selecting the text in the field,
then pressing:
PC: Control-C copy, Control-V paste.
Mac: Command-C copy, Command-V paste.

Error messages, if any, are displayed here.
Your Sound Speed Value Converted
This is the sound speed value resulting from conversion, with the speed units that are selected in the To menu. Calculator Memory You can save the result of your conversion in the Calculator Memory, then use your saved results later as input for other converters and calculators anywhere on the website. See the Calculator Memory for more details. TIP:
Precision of the converter is 12 significant digits, from left to right. Digits after the 12 left-most digits, are not significant.
Numeric Range of the converter is:
+1.797e+308 to -1.797e+308
+1.000e-311 to -1.000e-311

Error messages, if any, are displayed here.
Control Buttons
The sound speed converter has three control buttons. Decimal and Scientific buttons let you choose the output format, as one of these two: Decimal: -9999.1 Scientific Notation: -9.9991e3 Decimal Button – In this mode the converter will output in Decimal format whenever possible.However, the converter will automatically output in Scientific Notation when the results cannot be shown properly in Decimal format. Scientific Button – In this mode the converter will always output in Scientific Notation. Convert Button – Convert the sound speed value that you entered above, by using any of these methods:
- Click the Convert button
- Select a different unit in the From menu
- Select a different unit in the To menu
- Click the Decimal or the Scientific button
- Press Enter or Return on keyboard
TIP:
Scientific Notation is better for visualizing and working with big and small numbers, compared to decimal format.
