# Velocity calculator: `BMW M5 top speed: 330 km/hr`

This calculator helps you estimate the distance travelled after a certain time of constant speed. It also converts to alternative speed units: mile/hr, km/h, m/s, mach, ...

### Speed

##### METRIC (DECIMAL)

Most countries use the Metric System, which uses the measuring units such as meters and grams and adds prefixes like kilo, milli and centi to count orders of magnitude.

• Speed = `91.7 m/s`
• Speed = `9.17 * 101 m/s (scientific)`
• Speed = `91.67 m/s (engineering)`
• ##### IMPERIAL

In the USA and UK, the older Imperial system is used, where things are measured in feet, inches and pounds.

• Speed = `330 026 m/hr`
• Speed = `301 ft/sec`
• ### Time

• Time = `3 600 secs` = `1.0 hrs`
• = `3.6 * 103 sec(s)`
• = `60 min(s)`
• = `1 hr(s)`
• ### Speed x Time = Distance

• Distance = `330 026 meter`
• = `1.08 * 106 ft`
• = `360.92 * 103 yard`
• = `330.03 * 103 m`
• = `330.03 km`
• = `205.07 mile`
• = `178.2 nautical mile`
