1 Meters to Feet

One meter is 3.28084 feet

One meter is 3.28084 feet. The math is a division: the international foot is fixed at exactly 0.3048 m by the 1959 yard and pound agreement, a figure NIST lists on its survey foot page, and 1 / 0.3048 = 3.28083989501312. Round that to six digits and you get the 3.28084 on converters, road signs and shipping labels. The meter on the other side of the ratio is defined by the speed of light in a vacuum, as the BIPM SI brochure sets out, so neither unit drifts.

In smaller units one meter is 39.3701 inches, 100 centimeters or 1,000 millimeters. It is 1.0936 yards, which makes it 8.56 cm longer than a yard, and 0.000621371 miles. The feet-and-inches reading, 3 ft 3.37 in, is the one that matters when you hold a US tape measure against something built to a metric drawing.

The factor only looks messy because the foot is the odd unit. A meter is a clean 100 cm, and a foot is a clean 30.48 cm, so the conversion is exact on both ends and the repeating decimal comes from dividing 100 by 30.48.

3 feet 3.37 inches on a tape measure

Split 3.28084 into whole feet and a leftover. The whole part is 3 ft. The 0.28084 that remains, times 12, is 3.3701 in, so one meter reads 3 ft 3.37 in. On a tape marked in sixteenths the nearest mark is 3 3/8 in, because 3/8 in is 3.375 and the true remainder is 3.370. The gap is 0.005 in, roughly the thickness of a sheet of paper, so a carpenter who calls it 3 ft 3 3/8 in is not making a mistake.

Read the other way, one meter is 39 3/8 in on a steel rule, a shade under 39.5 in. That half inch matters when a 40 in door opening has to take a 1 m wide appliance: the appliance is 39.37 in, so it clears by 0.63 in, or 16 mm, before you allow for the door stop and hinge side clearance.

Mixed heights convert the same way. 1.5 m is 4.9213 ft, which is 4 ft 11.06 in, so a shelf set at 1.5 m sits a hair below the 5 ft mark. A person listed at 1.8 m is 5.9055 ft, or 5 ft 10.87 in, which is why gym charts and passport forms pair 1.8 m with 5 ft 11 in. Add the inches first, divide by 12, then multiply by 0.3048 and you get the same answer with one less rounding step.

What a meter looks like in a room

A meter is a useful yardstick for furniture because so many metric catalogs list depth and width in whole centimeters. Kitchen counters are 24 in deep in the US, which is 61 cm, so a 1 m deep counter is 39.4 in and sticks out almost 15 in further than the standard run. A sofa listed at 100 cm deep is 39.37 in deep, and most living rooms want 36 to 40 in of walking space in front of it.

Doors are where the two systems meet with a bang. A US interior door is 80 in tall, or 2.03 m, while a European door is usually 2.0 m, or 78.74 in. The 1.26 cm difference is enough that a US slab will not drop into a metric frame without trimming. A 1 m wide doorway is 39.37 in, wider than the 32 to 36 in opening in most US homes.

Beds show the same pattern. A twin mattress is 75 in long, or 190.5 cm, and a queen is 80 in, or 203 cm. A 1 m wide bed is 39.37 in, narrower than a twin, which is why metric hotel listings pair 90 cm with a single and 140 cm with a double. If you are buying a rug for a room measured in meters, 1 m by 2 m is 3.28 ft by 6.56 ft, close to a 3 by 6 ft runner.

Fabric, trim and rope sold by the meter

Fabric is the one place where a meter and a yard sit side by side on the same shelf. A meter is 1.0936 yd, so a meter gives you 9.4 percent more cloth than a yard, and a pattern that calls for 2 1/2 yd needs 2.286 m. Buying 2.5 m leaves a small margin, which is why quilters who work from US patterns and shop in metric stores add a quarter meter to every cut.

Fabric width is usually printed in inches even in metric shops: 44/45 in wide cloth is 112 to 114 cm, and 60 in wide cloth is 152 cm. A 1 m length of 45 in fabric is a rectangle 100 by 114 cm, or 39.37 by 44.88 in. Ribbon and bias tape sold by the meter are narrower: 1 m of 1 in ribbon is 39.37 in of trim, enough to edge one placemat with a little waste.

Rope, chain and cable follow the same rule. One meter of 3/8 in rope is 39.37 in, and a 100 ft coil is 30.48 m, so three 10 m cuts leave 0.48 m, about 19 in, at the end. When a job calls for 10 ft and the hardware store sells by the meter, buy 3.1 m rather than 3 m, because 3 m is 9.84 ft and comes up 1.9 in short.

Water depth, pools and weather reports

News reports in metric countries give flood depth in meters, and 1 m of water is 3.28 ft, deep enough to reach the door handle of most sedans and well past the 12 in that stalls a car engine. A pool with a 1 m shallow end is 3.28 ft, a typical US shallow end is 3 ft or 0.91 m, and a 1 m diving depth is 3.28 ft, which is why metric pool signs read 1.0 m where US signs read 3 ft 3 in.

Depth also means pressure. One meter of water column pushes 9.8 kPa, or 1.42 psi, against a pool wall, and every extra meter adds the same amount. That is the number behind the rule that a 1 m deep tank needs walls twice as strong as a 0.5 m deep one, not four times, because pressure scales with depth rather than volume.

Rain gauges split along the same line. A storm that drops 1 in of rain has dropped 2.54 cm, and a forecast of 25 mm is 0.98 in, close enough that most people treat them as the same. Snow is different: 1 in of liquid water makes roughly 10 in of snow at the 10 to 1 ratio forecasters often quote, so 2.54 cm of water can become 25 cm of snow on the driveway.

Meters to feet in your head

The head math is triple, then add a tenth. Three times 1 m is 3 ft, and the true factor is 9.36 percent above 3, so 3 ft plus 9.4 percent gives 3.28 ft. The same trick on 10 m gives 30 plus 2.8, or 32.8 ft, against the exact 32.81. On 100 m it gives 328 ft against 328.08, which is close enough for a track or a field.

Going the other way, multiply feet by 0.3 and add a sliver. Ten feet is 3.0 plus 0.048, or 3.048 m. Twenty feet is 6.0 plus 0.096, or 6.096 m. The sliver is 1.6 percent of that meter figure, so 50 ft is 15 plus 0.24, or 15.24 m, which is exact. Past a few hundred feet the shortcut still works, but the rounding to 0.3048 is what you want on a cut list.

Two anchor numbers cover most everyday checks. A meter is a little over 3 ft, and a meter is a little under 40 in. Anything that reads 1 m on a metric label will read 3.3 ft or 39.4 in in a US store, and a 3 ft object is 0.914 m, so the two are close but never interchangeable on a tight fit.

The same factor applied in one-foot steps, rounded to three decimals, which is enough for a tape measure or a room plan:

Every feet cell is the meters cell times 3.28084, and the inch part is the decimal remainder of the feet times 12, so 3.28084 ft becomes 3 ft plus 0.28084 x 12 = 3.37 in.

Meters to feet and inches, 1 m to 2.5 m

The table below covers the meter values that come up most often in listings, gym charts and furniture specs. Each row is the meter value times 3.28084 for feet, and the inches column is the leftover fraction of a foot times 12.

Read 1.7 m as 5 ft 6.93 in and you can see why a 5 ft 7 in person is often listed as 1.7 m. The rounding goes both ways: 5 ft 7 in is 1.702 m, so either label describes the same body within 2 mm. For a doorway, a fit that tight deserves the exact value rather than the rounded one.

Square and cubic meters use a different number

Area and volume do not convert with 3.28084. One square meter is 10.7639 square feet, because the factor is squared, and one cubic meter is 35.3147 cubic feet, because it is cubed. A 1 m by 1 m tile is 3.28 ft by 3.28 ft, or 10.76 sq ft, and a box of flooring that covers 1 m2 covers 10.76 sq ft, not 3.28.

Volume trips people up in concrete and soil orders. One cubic meter is 1.30795 cubic yards, so a 1 m3 delivery is about 1.31 yd3, and a 2 yd3 order is 1.53 m3. A raised bed 1 m long, 1 m wide and 0.3 m deep holds 0.3 m3, which is 10.59 cubic feet or 0.39 yd3, so two 40 lb bags of soil at 0.75 cu ft each will not fill it.

For weight, the meter only enters through density. A cubic meter of water is 1,000 kg, or 2,204.6 lb, and a cubic meter of dry topsoil is about 1,300 kg, or 2,866 lb. That is why a 1 m3 bulk bag of soil weighs more than a ton and why the delivery truck cares about the number even when you only ordered a small bed.
