# Distance: Tesla Model-S P85D Top Speed: 250 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 = `69.4 m/s`
• Speed = `6.94 * 101 m/s (scientific)`
• Speed = `69.44 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 = `250 000 m/hr`
• Speed = `228 ft/sec`
• ### Time

• Time = `86 400 secs` = `1.0 day`
• = `86.4 * 103 sec(s)`
• = `1.44 * 103 min(s)`
• = `24 hr(s)`
• = `1 day(s)`
• ### Speed x Time = Distance

• Distance = `6 000 000 meter`
• = `6.56 * 106 yard`
• = `6 * 106 m`
• = `6 * 103 km`
• = `3.73 * 103 mile`
• = `3.24 * 103 nautical mile`
