About Meter per Hour (m/s)
The meter per hour (m/h) is an extremely slow unit of speed, rarely used in everyday contexts but useful for expressing very gradual movement — geological processes, biological growth, or slow industrial feed rates. One meter per hour is about 0.001 km/h or 0.00028 m/s. Glaciers move at roughly 100–3,000 m/h (0.1–3 m per hour is typical). Snails travel at about 50 m/h. The unit provides a convenient scale for phenomena that would otherwise require small decimals in m/s or km/h.
A garden snail moves at roughly 50 m/h. A glacier advances at 100–1,000 m/h depending on the ice sheet.
About Meter per Second (m/s)
The meter per second (m/s) is the SI base unit of speed, expressing how many meters an object travels in one second. It is the standard unit in physics, engineering, and scientific contexts. Most everyday speeds feel small in m/s — a brisk walk is about 1.4 m/s, a bicycle around 5–7 m/s, a car on a motorway around 30 m/s. The unit scales cleanly through SI prefixes and converts directly to other metric speed units: 1 m/s = 3.6 km/h. Wind speed in meteorology is often reported in m/s in scientific literature.
A sprinter running 100 m in 10 seconds averages 10 m/s. A gentle walking pace is about 1.4 m/s.
Meter per Hour – Frequently Asked Questions
How fast does a glacier move in meters per hour?
Most valley glaciers advance at 20–200 m/h (0.5–5 m/day). Surge glaciers — which periodically accelerate — can reach 1,000–10,000 m/h for months at a time. The Jakobshavn Glacier in Greenland holds the record for the fastest sustained glacier flow at roughly 4,600 m/h (46 m/day). For context, that's still far slower than a garden snail.
How fast does hair grow in m/h?
Human scalp hair grows at roughly 15 cm per year — about 0.017 mm/hour, or 0.000017 m/h. Nails grow at about half that rate. At this scale, even the m/h unit is too large; growth biologists use mm/day or cm/month. The fastest-growing human tissue is bone marrow, not hair.
What moves at around 1 meter per hour?
Some lava flows on gently sloping terrain advance at about 1 m/h. Tectonic plates move at 2.5–15 cm/year — far below even 1 m/h. Bread rising in a warm kitchen expands at a few mm/hour. Corrosion front advancement in protected steel structures can be tracked in mm or cm per year.
Is m/h the same as m/hr?
m/h and m/hr are both used for meters per hour — neither is an official SI notation, since the SI symbol for hour is h (not hr). The correct SI notation is m/h. In engineering documentation, m/hr appears frequently as a stylistic choice, particularly in American engineering texts that prefer "hr" over "h" for legibility.
How do you convert m/h to mm/day?
Multiply by 24,000. One m/h = 1,000 mm/h × 24 h/day = 24,000 mm/day. This conversion is useful in hydrology (soil permeability is measured in mm/day) and biology (plant growth, wound healing rates). A glacier moving at 100 m/h would be advancing 2,400,000 mm/day — or 2.4 km/day, which is an exceptionally fast surge.
Meter per Second – Frequently Asked Questions
How do you convert m/s to km/h?
Multiply by 3.6. The conversion comes from the unit chain: 1 m/s × 3,600 s/hr ÷ 1,000 m/km = 3.6 km/h. So 10 m/s is 36 km/h, and the motorway limit of 130 km/h is about 36.1 m/s. The factor 3.6 is one of the most useful quick conversions in physics.
What is the speed of sound in m/s?
Sound travels at about 343 m/s in dry air at 20°C. This varies with temperature — roughly 0.6 m/s per degree Celsius. In water, sound travels about 1,480 m/s; in steel, around 5,100 m/s. The Mach number expresses speed as a multiple of the local speed of sound.
How fast do Olympic sprinters run in m/s?
Usain Bolt's world record 100 m sprint averaged 10.44 m/s. His peak speed during the race was approximately 12.4 m/s (44.7 km/h), reached around the 60–80 m mark. For comparison, a greyhound runs at about 17 m/s and a cheetah peaks at 33 m/s.
Why do scientists use m/s instead of km/h?
The SI system requires a coherent base unit for all physics calculations. Using m/s keeps equations consistent — kinetic energy (½mv²), force (ma), and pressure (N/m²) all resolve cleanly in SI. Converting to km/h mid-calculation introduces factors of 3.6 that propagate through formulas and cause errors.
What is a fast wind speed in m/s?
The Beaufort scale defines gale force at 17–20 m/s (62–72 km/h). Hurricane-force begins at 33 m/s (119 km/h). The strongest surface wind ever recorded was 113 m/s (408 km/h) during Tropical Cyclone Olivia in 1996 on Barrow Island, Australia.
